Ball 1 collides head on with an another identical ball 2 at rest. Velocity of ball 2 after collision becomes two times to that of ball 1 after collision. The coefficient of restitution between the two balls is :
Text Solution
Verified by ExpertsThe correct answer is:
A
v 2 = 2v 1
(1 + e) u 1 = 2(1 – e)u 1
e =
