Question

A sphere A of mass m, travelling with speed v, collides directly with a stationary sphere B. If A is brought to rest and B is given a speed V, find (a) the mass of B (b) the coefficient of restitution between A and B?

Answer 1

Correct Answer - A::B
(a) `p_i=p_f`
`:. mv=MV`
`impliesM=(mv)/(V)`
(b) `e=(RVOS)/(RVOA)=V/v`
