Answer:

The the analysis for the free fall part should be done under the constant acceleration.

Explanation:

In the given problem, the jumper is falling under the free fall. Since, no external force is acting on the body therefore, the fall will be under the action gravity only. also, the acceleration due to gravity is always constant.

Therefore, the the analysis for the free fall part should be done under the constant acceleration.

A student who weighs 550 N is wearing a backpack that weighs 80 N. The student is standing still on level ground. Give your answ
siniylev [52]

Answer:

Explanation:

a) The magnitude of the net force on the student = 0 N since the student is standing still on level ground and upward reaction force = downward force.

b) the magnitude of the contact force on the student by the backpack = 80 N since the student was backing the backpack

c) the magnitude of the contact force o the student by the ground = 550 N + 80 N = 630 N reactional force on the student

How much force is required to produce a torque of 100 Nm if the force is applied at an angle of 40 at a distance of 25 cm from t
Fudgin [204]

Answer:

Force, F = 622.28 N

Explanation:

It is given that,

Torque, \tau=100\ N-m

Angle between force and displacement, \theta=40^{\circ}

Distance, d = 25 cm = 0.25 m

We need to find the force required to produce the torque. Torque produced by an object is given by :

\tau=Fd\sin\theta

F is force required to produce torque

F=\dfrac{\tau}{d\sin\theta}\\\\F=\dfrac{100}{0.25\times \sin(40)}\\\\F=622.28\ N

So, applied force is 622.28 N.
