A common classroom demonstration involves holding a bowling ball attached by a rope to the ceiling close to your face and releasing it from rest. In theory, you should not have to worry about being hit by the ball as it returns to its starting point. However, some of the most "exciting" demonstrations have involved the professor being hit by the ball!
(a) Why should you expect not to be hit by the ball?
     Correct: Your answer is correct.

(b) Why might you be hit if you actually perform the demonstration?
     Correct: Your answer is correct.

The figure below shows four situations in which a box slides to the right a distance d across a frictionless floor as a result of applied forces, one of which is shown. The magnitudes of the forces shown are identical. Rank the four cases in order of decreasing work done on the box during the displacement by the force shown. (Use only ">" or "=" symbols. Do not include any parentheses around the letters or symbols. Refer to each case by its corresponding letter only.)
Incorrect: Your answer is incorrect.

A 12-kg block (M) is released from rest on a frictionless incline that makes an angle of 20°, as shown in the figure below. Below the block is a spring that has a spring constant of 14000 N/m. The block momentarily stops when it compresses the spring by 5.0 cm. How far does the block move down the incline from its rest position to the stopping point?
m
