Answer:

Abdul has an apparent weight of 600 newtons.

Explanation:

The statement is incorrectly written. Its correct form is:

Abdul of mass 50 kg is standing in an elevator of his building. The elevator is moving upwards and is slowing down at a rate of 2.0 m/s2. What is Abdul's apparent weight? Use g = 10 m/s2.

According to the statement, we know that elevator and Abdul himself are moving upwards and decelerating, which means that Abdul feels a force from elevator is the same direction of his weight. From 2nd Newton's Law we find the following equation of equilibrium:

[tex]\Sigma F = F-m\cdot g = m\cdot a[/tex] (1)

Where:

[tex]F[/tex] - Apparent weight, measured in newtons.

[tex]m[/tex] - Mass of Abdul, measured in kilograms.

[tex]g[/tex] - Gravitational acceleration, measured in meters per square second.

[tex]a[/tex] - Net acceleration of the elevator-Abdul system, measured in meters per square second.

In (1) we clear the apparent weight:

[tex]F = m \cdot (a+g)[/tex]

If we know that [tex]m = 50\,kg[/tex], [tex]a = 2\,\frac{m}{s^{2}}[/tex] and [tex]g = 10\,\frac{m}{s^{2}}[/tex], we find that the apparent weight of Abdul is:

[tex]F = (50\,kg)\cdot \left(2\,\frac{m}{s^{2}}+10\,\frac{m}{s^{2}} \right)[/tex]

[tex]F = 600\,N[/tex]

Abdul has an apparent weight of 600 newtons.

Answer:

400N is applied to the rope

Answer:

300N

Explanation:

Assuming his friend didn't throw the box, they would need a total of 1,500N to lift it, if the first person is already applying 1,200N, the only other amount of force needed is 300N to make a total of 1,500N! Simple math problem :)

Answer:  Kinetic energy is energy that an object has as a result of its motion. Potential energy is stored energy that has not yet been released.

Answer:

a. 2 kg*m/s

b. [tex]p_{T_{f}} = 0.5v_{f} = 2 kg*m/s[/tex]

c. 4 m/s

Explanation:

a. The momentum of the system ([tex]p_{Ti}[/tex]) before the blob of clay strikes the cart is:

[tex] p_{Ti} = p_{b} + p_{c} [/tex]

Where:

[tex]p_{b}[/tex] is the momentum of the blob clay

[tex]p_{c}[/tex] is the momentum of the car      

[tex] p_{Ti} = m_{b}v_{b} + m_{c}v_{c} [/tex]

Since the car is initially at rest, [tex]v_{c}[/tex] = 0

[tex] p_{Ti} = 200 g*\frac{1 kg}{1000 g}*10 m/s + 0 = 2 kg*m/s [/tex]

b. The momentum of the system after they come together:

[tex]p_{T_{f}} = m_{b}v_{b} + m_{c}v_{c}[/tex]

Since they come together, [tex]v_{b}[/tex] =

[tex]p_{T_{f}} = v_{f}(m_{b} + m_{c}) = v_{f}(0.2 kg + 0.3 kg) = 0.5v_{f}[/tex]   (1)

Because we do not have the final speed we can not calculate the final momentum.

c. We can find the speed of the clay and car by conservation of the momentum:

[tex] p_{i} = p_{f} [/tex]

The initial momentum of the system was founded in part "a" (p = 2 kg*m/s), so we have:

[tex] 2 kg*m/s = m_{b}v_{b_{f}} + m_{c}v_{c_{f}} [/tex]

Again, when they come together, the final speed is the same:

[tex] 2 kg*m/s = v_{f}(m_{b} + m_{c}) [/tex]                

[tex] v_{f} = \frac{2 kg*m/s}{0.2 kg + 0.3 kg} = 4 m/s [/tex]

Now, since we found the final speed we can calculate the momentum of the system after they come together (equation 1):        

[tex] p_{T} = 0.5v_{f} = 0.5 kg*4m/s = 2 kg*m/s [/tex]

Answer:

22.777777777777 m/s

Explanation:

Since 1 kilometer is 1000 meters, then 82 km is 82000 meters. Since one hour is the same as 3600 seconds, then the answer is pretty simple: 82000/3600 or 820/36. That gets you 22.77777 or 22.78. Hope this helps

Answer:

  bust

Explanation:

At the same speed, kinetic energy is proportional to mass. The more massive object (the large bust) will have more kinetic energy.

Answer:

Bust

Explanation:

the kinetic energy of an object is the energy that it possesses due to its motion. It is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity. Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes. The same amount of work is done by the body when decelerating from its current speed to a state of rest.

The emotional symptoms that may occur in those with a Schizophrenic disorder generally include all of the following except appropriate emotion. Hence, option (B) is correct.

Schizophrenia is a persistent, severe mental illness that has an impact on a person's relationships with others as well as their thinking, acting, and emotional expression. Despite not being as prevalent as other severe mental illnesses, schizophrenia can be the most persistent and incapacitating.

Schizophrenia patients frequently struggle to function well in relationships, the workplace, and academic settings. They can appear to have lost their sense of reality, feel afraid and withdraw. This chronic illness cannot be cured, but it can be managed with the right care.

A cannonball is shot from the top of a 47.8 m high hill at a speed of 53.7 m/s. The height then is 61.81 m/s.

The motion of an object with constant acceleration is described by a set of equations known as kinematic equations. Integrals, derivatives, and rates of change must all be understood in order to solve kinematics equations.

Velocity is the rate and direction of an object's movement, whereas speed is the time rate at which an object is moving along a path. In other words, velocity is a vector, whereas speed is a scalar value.

The kinematic equation is:

v² = u² + 2gs (a = g)

Where u is the initial velocity, a is the acceleration, and v is the velocity after the time period t.

(53.7)² + 2 x 9.8 x 47.8 m

Therefore, the height is 61.81 m/s.

it’s 144.2 I have it in my notes from when I was in school!!!!

Answer:

t = 2.38 [s]

Explanation:

To solve this problem we must use the following equation of kinematics. We must clarify that both the acceleration and the initial velocity were taken as positive, since the velocity of the movement coincides with the direction of the acceleration.

[tex]x =x_{o} +v_{o} *t+(\frac{1}{2} )*a*t^{2}[/tex]

where:

x - Xo = distance = 47 [m]

Vo = initial velocity = 8 [m/s]

a = gravity acceleration = 9.81 [m/s²]

t = time [s]

Now replacing these values in the equation:

47 = 8*t + 0.5*9.81*t²

47 = 8t + 4.905t²

47 = 4.905*t(1.63 + t)

9.58 = t*(1.63 + t) solving this equation (cuadratic)

we found that t = 2.38 [s]

Answer:

V = 1280 [V]

Explanation:

To solve this problem we must use ohm's law which tells us that the voltage is equal to the product of the resistance by the current.

Therefore we have:

V = I*R

where:

V =  voltage [V] (Units of volts)

I = current = 4 [amp]

R = resistance = 320 [ohms]

V = 4*320

V = 1280 [V]

Explanation:

Net Force

Newton's second law explains the dynamics principles when a number of forces are applied to an object.

The net force vector is the sum of the individual vector forces applied. The magnitude of the net force is related to the magnitude of the acceleration of the body as follows:

[tex]Fn=m.a[/tex]

Furthermore, the acceleration can be calculated if we know the kinematic behavior of the body:

[tex]\displaystyle a=\frac{v_f-v_o}{t}[/tex]

Where vf, vo, and t are the final speed, initial speed, and time, respectively.

The box is pushed across the floor with a force of 25 N against a frictional force of 14 N.

The net force applied to the box is:

[tex]Fn = 25 N - 14 N = 11 N[/tex]

We also know the box is accelerated from rest (vo=0) to vf=4 m/s in t=16 seconds, thus:

[tex]\displaystyle a=\frac{4-0}{16}[/tex]

[tex]a = 0.25~m/s^2[/tex]

From the equation:

[tex]Fn=m.a[/tex]

We solve for m:

[tex]\displaystyle m=\frac{Fn}{a}=\frac{11~N}{0.25~m/s^2}[/tex]

[tex]\mathbf{m = 44~Kg}[/tex]

Answer:

a' = 3a

Explanation:

Newton's Second Law gives the magnitude of the unbalanced force applied to an object as follows:

F = ma

where,

F = Force Applied

m = Mass of Object

a = acceleration

FOR RAMONA'S PUSH:

F = F

m = m

a = a

Therefore,

F = ma  

a = F/m   ---------------- equation (1)

FOR FRANSICO'S PUSH:

F = 3F

m = m  (mass of turtle will be same)

a = a'

Therefore,

3F = ma'  

a' = 3F/m

using equation 1

a' = 3a
