Momentum and CollisionHardBloom L3
Question
Two billiard balls undergo a head-on collision. Ball 1 is twice as heavy as ball 2. Initially, ball 1 moves with a speed v towards ball 2 which is at rest. Immediately after the collision, ball 1 travels at a speed of v/3 in the same direction. What type of collision has occurred?
Options
A.inelastic
B.elastic
C.completely inelastic
D.cannot be determined from the information given
Solution
Sol. 
$v_{1}^{'} = (1 + e)v_{C} - v_{1}$
$\frac{v}{3} = (1 + e).\frac{2v}{3} - e^{V} \Rightarrow e = 1$
