Question
Two cars (A and B) of equal mass have an elastic
collision. Prior to the collision, car A is moving at 15 m/s in the
+x-direction, and car B is moving at 10 m/s in the –x-direction.
Assuming that both cars continue moving along the x-axis
after the collision, what will be the velocity of car A after the
collision?
a. same as the original 15 m/s speed, opposite direction
b. equal to car B’s velocity prior to the collision
c. equal to the average of the two velocities, in its original
direction
d. equal to the average of the two velocities, in the
opposite direction
