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.

The work done on both eggs is the same because work is related to the change in kinetic energy, which is the same for both eggs as they have the same mass and initial velocity.
