The best exercise for Alicia to add to her routine will be biking with occasional sprints. Thus, the correct option is A.

Anaerobic exercise is a type of exercise which involves breaking down of the glucose sugar in the body without using the oxygen gas. Anaerobic means without oxygen, the exercises which does not require oxygen. In practical terms, it means that anaerobic exercise is more intense exercise, however shorter in duration than that of aerobic exercise.

Alicia’s coach thinks that she should try some interval training so that she can get some anaerobic activity. The activity which should be added to her routine is biking with occasional sprints.

Therefore, the correct option is A.

When finding work (J) given force (N), we use the equation:

W = FdcosФ <-- Only take into account the force in the direction of motion

Plug in the given values:

W = 27(32)cos(20) = 811.89 J

Explanation:

Here,

Given that,

pulls a wagon a distance of 32 meters the handle is above an angle of 20 degrees above horizontal if you pull on it with a force of 27 N

To find,

As we know that,

[tex]{\boxed{\sf{W=f.d.cos\theta }}}[/tex]

According to the question,

[tex]W=27(32)cos{20}\\\\w=811.89J[/tex]

Answer: KE = 34.425 kJ

Explanation:

KE = (1/2) mv^2

KE = (0.5)*(34kg)(45m/s)^2

KE = (0.5)*(34kg)(2025m^2/s^2)

KE = 34425 kg*m^2/s^2

1 Joule = 1 kg*m^2/s^2

KE = 34.425 kJ

The kinematics allows finding the result for the height of the cliff so that the bodies go down together is: 1,533 m

Kinematics studies the movement of bodies, finding relationships between the position, velocity and acceleration of bodies

In this case the bodies are thrown vertically so their acceleration is the gravity acceleration, directed downwards.

Let's set a reference system with the positive upward direction and zero at the base of the cliff, let's use the subscript 1 for the body that comes out from the bottom of the cliff and the subscript 2 for the body that comes out of the top, the equations for each body they are:

body 1

            [tex]v_1^2 = V_{o1}^2 - 2g (y_1-y_{o1} )[/tex]

body 2

             [tex]v_2^2 = v_{o2}^2 - 2g (y_2-y_{o2})[/tex]

In this case they indicate the initial velocities of each body, [tex]v_{o1}[/tex] = 80 m/s and [tex]v_{o2}[/tex] = 50 m/s, the initial height [tex]y_{o1}[/tex] = 0 and [tex]y_{o2}[/tex] = h, when the bodies fall at the same time they must begin to descend from the same height

            y₁ = y₂

The velocities at this point must be zero

          v₁ = v₂ = 0

We substitute

            0 = [tex]v_{o1}^2 - 2 g y[/tex]

            0 = [tex]v_{o2}^2 - 2 g ( y + h)[/tex]  

Let's solve the system of equations

            [tex]h = \frac{v_{o1} - v_{o2}}{2g}[/tex]  

Let's calculate

            h = [tex]\frac{80-50}{2 \ 9.8}[/tex]

            h = 1.53 m

Consequently, the kinematics allows finding the result for the height of the cliff so that the bodies go down together is: 1.53 m

Hello!

We can begin by summing the forces acting on each mass. (Tension is CONSTANT because the string is both frictionless and massless).

On the 3 kg block: (Ignore forces acting in the vertical direction since there is no motion in that axis)

∑F = -M₁gsinФ + T

On the 8 kg block:

∑F = -T + M₂g

Sum the forces:

∑F = -M₁gsinФ + T -T + M₂g

∑F = -M₁gsinФ + M₂g

Divide by both masses to get the acceleration:

[tex]a = \frac{-M_1gsinФ + M_2g}{m_1+m_2}[/tex]

Plug in values: (g = 10m/s²)

[tex]a = \frac{-(3)(10)(sin30)+8(10)}{3+8} = 5.91 m/s^2[/tex]

Answer:

mass = 25.5kg

Explanation:

The gravitational force equivalent, or, more commonly, g-force, is a measurement of the type of force per unit mass – typically acceleration – that causes a perception of weight, with a g-force of 1 g equal to the value of gravitational acceleration on Earth, g, of about 9.8 m/s².

Mass, m = [tex]\frac{Force}{acceleration due to gravity}[/tex]

[tex]mass,m=\frac{F}{g} = \frac{250}{9.8}= 25.5 kg[/tex]

Answer: The  dependent variable. Dependent variables (DV): These are the factor that you observe or measure.

Explanation:

These are the factors or conditions that you manipulate in an experiment. Your hypothesis is that this variable causes a direct effect on the dependent variable. Dependent variables (DV): These are the factor that you observe or measure.

Answer:

I believe the answer succumbs to the hypothesis. More over, I actually believe the answer should be the independent variable since that makes so much more sense.

Explanation:

Answer:

Below

Explanation:

Here is what we are given in the problem :

dy = - 1.0 m (this is negative because the cat falls)

Vx = 5.0 m/s

We can use this equation to find the time that it will take the cat to fall :

     t = √-2dy / g

     t = √-2(-1.0) / 9.8

     t = √0.20408

     t = 0.45 (round this to 2 sig figs)

    t = 0.5 seconds

Now we can find dx (distance in the x direction)

     dx = vx (t)

     dx = (5.0m/s)(0.45s)

     dx = 2.258769 m

     dx = 2.3 m

Answer:

Using Pythagorean Theorem.

[tex]F_{R} = \sqrt{Fn^{2} + Fe^{2} } \\\\ F_{R} = \sqrt{52.7^{2} + 91^{2} }\\\\ F_{R} = 105.16N[/tex]

b)

Answer:

[tex]tan^{-1} \frac{opp}{adj} \\ \\ tan^{-1} \frac{52.7}{91} \\ \\ = 30.08^{o}[/tex]

The resultant force of the two forces which are acting perpendicular to each other is 105.15 N and the direction is 59.91 ° from east.

Force is an external agent acting on a body to change it from the state of motion or rest. If two forces acting on a body and both are applied in the same direction, the resultant force will be the sum of two forces in magnitude.

If the two forces are in opposite directions, then the resultant force will be the substracted value of their magnitude. If one force is to the north and other is to the east, then they are perpendicular to each other.

Hence, to find the resultant force we can use the Pythagoras theorem for right angled triangle. The hypotenuse will be the resultant force.

Resultant force = √ (52.7² + 91² )

                          = 105. 15 N.

The direction of the force = Tan ⁻¹ (91 / 52.7 )

                                           = 59.91 ° from east to north.

Hence, the resultant force is 105.15 N with a direction of 59.91 ° from east.
