Question

A ball of mass moving with speed perfectly inelastically with another ball of measure at rest . The magnitude of impulse imparted first ball is

Answer 1

The collision is perfectly inelastic Both of'em will stick together!

Then,

V = velocity of the combined mass.

Therefore,

mv = (M + m)V

V = (m/M+m)v

Impulse imparted to the 1st ball will be

MV = MmV / m+M
