Question

A billiard ball rolling across a table at 1.55 m/s makes a head-on elastic collision with an identical ball. Find the speed of each ball after the collision when each of the following occurs.

(a) The second ball is initially at rest.
first ball     m/s
second ball     m/s

(b) The second ball is moving toward the first at a speed of 1.05 m/s.
first ball     m/s
second ball     m/s

(c) The second ball is moving away from the first at a speed of 0.90 m/s.
first ball     m/s
second ball     m/s
