upper delta
Hello can you please explain me this question.
Three identical spheres are lying in the same straight line. The coefficient of restitution between any pair of spheres is 1/2. Initially the left-hand sphere has a velocity of 2 ms' towards the other two which are both stationary. What are the final velocities of all three, when no more collisions can occur?
The answers are 13/32, 15/32, 9/8
