List of top Physics Questions on Elastic and inelastic collisions asked in TS EAMCET

A body P of mass \(1.5\text{ kg}\) moving with velocity \(10\text{ ms}^{-1}\) makes a one dimensional elastic collision with another body Q at rest. If ratio of velocities after collision is \(1:3\), then velocity of centre of mass is

In analysing the problems of inelastic collisions, the law of conservation of momentum and the law of conservation of mechanical energy are to be employed Since the laws of conservation of momentum and mechanical energy are fundamental laws, they should hold good in any situation. Which of the following is true?
