explain the relationship between mass and acceleration

Answers

Answer 1

Answer:

Explanation: Newton's second law of motion pertains to the behavior of objects for which all existing forces are not balanced. The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased.

Answer 2

Answer:

[tex]\huge\boxed{\sf Inverse \ Relation}[/tex]

Explanation:

According to Newton's Second Law Of Motion:

"The acceleration produced by the body is directly proportional to the force acting on the body and inversely proportional to mass."

So, The Mathematical Form will be:

Acceleration ∝ [tex]\sf \frac{1}{mass}[/tex]

So, Acceleration and mass are inversely proportional. This means that Greater the mass, Smaller will be the acceleration produced and vice versa.

[tex]\rule[225]{225}{2}[/tex]

When a 0.622 kg basketball hits the floor, its velocity changes from 4.23 m/s down to 3.85 m/s up. If the average force was 72.9 N, how much time was it in contact with the floor?
(Unit = s)
Remember: up is +, down is -

Answers

Answer:

t = 0.0689 s

Explanation:

Given that,

Mass of a basketball, m = 0.622 kg

Initial velocity, u = 4.23 m/s (downward or negative)

Final velocity, v = 3.85 m/s (up of positive)

Average force, F = 72.9 N

We need to find the time it was in contact with the floor. The force is given by :

[tex]F=ma\\\\F=m\dfrac{v-u}{t}\\\\t=\dfrac{m(v-u)}{F}\\\\t=\dfrac{0.622\times (3.85-(-4.23))}{72.9}\\\\t=0.0689\ s[/tex]

So, the time of contact is 0.0689 s.

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor
a distance of 8.1 m. The force of friction between the refrigerator and the floor is
230 N. If the work was done in 55 seconds, what is the power of the mover?

Answers

Given :

A mover slides a refrigerator weighing 650 N at a constant velocity across the floor a distance of 8.1 m.

The force of friction between the refrigerator and the floor is 230 N.

To Find :

How much work has been performed by the mover on the refrigerator.

Solution :

Since, refrigerator is moving with constant velocity.

So, force applied by the mover is also 230 N ( equal to force of friction ).

Now, work done in order to move the refrigerator is :

[tex]W = Force\times distance\\\\W = 230 \times 8.1\ N\ m\\\\W = 1863\ N\ m[/tex]

Hence, this is the required solution.

what polarity must the red tip of the compass needle be since it points toward the south pole of the magnet?

Answers

Answer: positive

Explanation: because opposites attract and north=positive and south=negative the answer should be positive.

The polarity of the red tip of the compass needle must be at the north of the earth, since it points toward the south pole of the magnet.

What is meant by polarity of a magnet ?

Polarity of a magnet is defined as the orientation of both the north and south poles of the magnet in space.

Here,

We know that, the opposite poles attract.

The magnetic needle is arranged in a such a way that, the red tip of the magnetic compass needle is actually pointing towards the geographic north pole of the earth.

In order to point the compass needle towards the magnetic south pole, the south pole of the magnet must be located in the geographic north pole.

Hence,

The polarity of the red tip of the compass needle must be at the north of the earth, since it points toward the south pole of the magnet.

Rodney hits a 0.060 kg tennis ball straight up with a speed of 15 m/s from a height of 2.2 m above the ground. How fast is the ball going when it is 9.5 m above the ground?

Answers

Answer:

Explanation:

From the question we are told that

   The mass of the tennis ball is  [tex]m = 0.060 \ kg[/tex]

    The speed is  [tex]u = 15 \ m/s[/tex]

    The initial height of the ball is  [tex]h_o = 2.2 \ m[/tex]

     The height considered is  [tex]h = 9.5 \ m[/tex]

Generally the time taken to reach the considered height is mathematically evaluated from the equation of motion as follows

           [tex]h = h_o + ut - \frac{1}{2} gt^2[/tex]

=>         [tex]9.5 = 2.2 + 15t - \frac{1}{2} * 9.8 t^2[/tex]

=>         [tex]7.3 = 15t - 4.9t^2[/tex]

=>          [tex]4.9t^2 -15t + 7.3[/tex]

solving the above equation using quadratic formula

           [tex]t= 0.6070 \ s[/tex] and  [tex]t_1 = 2.454 \ s[/tex]

Generally from kinematic equation we have that

        [tex]v = u - gt[/tex]

=>     [tex]v= 15 - 9.8 * 0.6070[/tex]

=>      [tex]v= 9.0514 \ m/s[/tex]

Note if we had used the second values of time the velocity at 9.5 \ m would have been negative which is not correct given that at maximum height velocity is zero

A 0.17 kg ball of dough is thrown straight up into the air with an initial speed of 12 m/s. The acceleration of gravity is 9.81 m/s 2 . a) What is its momentum at its maximum height? Answer in units of kg · m/s

Answers

Answer:

The momentum of the ball at the maximum height is zero (0 kg.m/s).

Explanation:

Given;

mass of the ball, m = 0.17 kg

initial velocity of the ball, u = 12 m/s

acceleration due to gravity, g = 9.81 m/s²

At maximum height the final velocity of the ball, v = 0

Momentum of the ball at the maximum height is given as;

P = mv

P = (0.17)(0)

P = 0 kg.m/s

Therefore, the momentum of the ball at the maximum height is zero (0).

Chemical energy transformations take place from the outlet charger to the ringing phone.

Explanation:

chemical energy

While charging the mobile electrical energy gets transformed into chemical energy. Most of the contemporary mobile phone batteries are lithium-ion batteries where the power is saved by the chemical transformations in the ionic structure of the battery.  When the power gets into the mobile phone it is transformed and collected as chemical energy inside of the battery and when we utilize the mobile the earlier saved chemical energy is again transformed into electrical energy.

The energy transformation that takes place from the outlet charger to the

ringing phone is electrical energy from the outlet is converted to chemical

energy and back to electrical energy and sound energy when the phone is

being used and ringing.

The charger provides a source of electrical energy which gets converted to

chemical energy stored in the battery. During use, the chemical energy gets

converted to electrical energy to power the phone and to sound energy

when it rings with heat energy being dissipated also.

A car of mass 1000 kg travelling at a velocity of 25 m/s collides with another car of mass 1500kg which is at rest. The two cars stick and move off together. What is the velocity of the two cars after the collision?​

Answers

Answer:

The velocity of the two cars is 10 m/s after the collision.

Explanation:

Law Of Conservation Of Linear Momentum

The total momentum of a system of bodies is conserved unless an external force is applied to it. The formula for the momentum of a body with mass m and velocity v is

P=m.v

If we have a system of bodies, then the total momentum is the sum of them all

[tex]P=m_1v_1+m_2v_2+...+m_nv_n[/tex]

If some collision occurs, the velocities change to v' and the final momentum is:

[tex]P'=m_1v'_1+m_2v'_2+...+m_nv'_n[/tex]

In a system of two masses, the law of conservation of linear momentum  takes the form:

[tex]m_1v_1+m_2v_2=m_1v'_1+m_2v'_2[/tex]

If both masses stick together after the collision at a common speed v', then:

[tex]m_1v_1+m_2v_2=(m_1+m_2)v'[/tex]

The car of mass m1=1000 Kg travels at v1=25 m/s and collides with another car of m2=1500 Kg which is at rest (v2=0).

Knowing both cars stick and move together after the collision, their velocity is found solving for v':

[tex]\displaystyle v'=\frac{m_1v_1+m_2v_2}{m_1+m_2}[/tex]

[tex]\displaystyle v'=\frac{1000*25+1500*0}{1000+1500}[/tex]

[tex]\displaystyle v'=\frac{25000}{2500}[/tex]

v' = 10 m/s

The velocity of the two cars is 10 m/s after the collision.

Answer:

hello your question is incomplete below is the complete question

A 2.0 kg block starts from rest on a positive x axis 3.0m from the origin and thereafter has an acceleration given by a= 4.0i - 3.0jin m/s2. At the end of 2.0 s, its angular momentum about the origin is ______.

answer : L = ( 2 kg ) [(-18m^2/s)k]

Explanation:

velocity vector(v)  = (4.0i - 3.0j )(2.0s)

position vector(r) = ( 3.0m)i

determine the angular momentum about the origin

L = m ( r * v )

attached below is the detailed solution

Answer:

Angular momentum about the origin = [tex](-36kg.rad/s)k[/tex]

Explanation:

Given the acceleration,

[tex]v(t) = 4ti - 3tj[/tex]

So,

[tex]v(2) = 8i - 6j[/tex]

similarly,

[tex]x(t) = (3 + 2t^2) i - 1.5t^2 j[/tex]

so,

[tex]x(2) = 11i - 6j[/tex]

Angular momentum,

[tex]=mx(2)*v(2)\\\\=2*((-6x0-0x-6)i +(0x8-11x0)j +(11x-6--6x8)k)\\\\=2*(0i +0j -18k)\\\\=(-36kg.rad/s)k[/tex]
