Momentum and CollisionMedium
Question
Ball 1 collides head on with an another identical ball 2 at rest. Velocity of second ball after collision becomes two times that of 1 after collision. The coefficient of restitution between the two balls is :
Options
A.e = 1/3
B.e = 1/2
C.e = 1/4
D.e = 2/3
Solution
v2 = 2v1
(1 + e) u1 = 2(1 − e)u1
e = 1/3
(1 + e) u1 = 2(1 − e)u1
e = 1/3
