A body of mass 100kg moving with a velocity of 10m/s makes elastic collision wit ping pang ball of lighter mass. the velocity of ping pang ball after collision is?
Mass of one body = 100 kg
Velocity = 10 m/sec
Mass of other body at rest = 100 kg
Momentum = before collusion
=> 1000
Makes elastic collision wit ping pang ball of lighter mass .
The velocity of ping pang ball after collision is =
= 5 m/ sec .
Mass of the body after collusion = 200 kg .
Velocity of the system = v .
