Two eggs of equal mass are thrown at a blanket with equal velocity. Egg B hits the blanket but egg A hits the wall instead. Compare the work done on the eggs in reducing their velocities to zero.
 a. More work was done on A than on B.
  b. More work was done on B than on A.
  c. The amount of work is the same for both.
  d. It is meaningless to compare the amount of work because the forces were so different.
  e. Work was done on B, but no work was done on A because the wall did not move.

Question 2

The only force acting on a 1.8-kg body as it moves along the x axis is given by Fx = -(3.0x) N, where x is in m. If the velocity of the body at x = 0 is vx = +8.0 m/s, at what value of x will the body have a velocity of +4.0 m/s?
 a. 5.7 m
  b. 5.4 m
  c. 4.8 m
  d. 4.1 m
  e. 6.6 m
