1. A 5kg block is push up a rough, inclined surface by a constantforce of 20N. The surface is inclined at an angle of 15° and theforce is applied completely horizontally and parallel to theground below the incline. (Not parallel to the inclined surface).As a result, the velocity of the block increases from 0 m/s to 4m/s in a displacement of 10m.A)What work was done by the frictional force during thisdisplacement?B)What would have been the final velocity if friction was notpresent?C) Why was the final kinetic energy without friction higherthan the total kinetic energy with friction?

We will answer this question by identifying forces on the block through a free body diagram, and…

A grocery cart with a mass of 10 kg is being pushed at constant speed up a 25° ramp by a force Fp which acts parallel to the incline. (Ignore the friction) a. Draw a free-body diagram of the cart showing all the forces acting on it. b. Find the work done by each of the forces (W, Fn, Fp) on the cart if the ramp is 7.5 m long. Hints: The question is very similar to the question of a piano sliding down an incline discussed in class. However, here the object is pushed up the incline. The forces Fn = mgcos(0), and Fp = mgsin(0), so don't spend time getting these using Newton's 2nd law. Also, the weight is W = mg. c. Find the net work done on the cart.

4. This Olympic skeleton athlete slides down an icy track head first. The track has many twists and turns with a total height of 102.75 m. If the 99.375 kg man has a speed of 27 m/s at the bottom, what was the total work done on him by friction and air resistance slowing him down? (In other words, what was the energy lost to friction and air resistance?) He starts from rest at the top. Previous submissions:
