Define elastic collision

Define in elastic collision. Derive an expression for velocities for head-on elastic collision.

Which of the following is NOT an example of inelastic collision?

In inelastic collision,

Define coefficient of restitution and obtain its value for an elastic collision and a perferctly inelastic collision.

For perfectly elastic collision

State the expression of final velocity of 2 bodies having a head on elastic collision.

Discus the folwing as special cases of elastic collision and obtain their exact or approximate final velocities in terms of their initial velocities.

When a massive body suffers an elastic collision with a stationary light body, then massive body approximately comes to rest and light body

Define coefficient of restitution. State its value in case of an inelastic collision.

A body P of mass 3 kg and moving with velocity of 2 m//s makes a head-on elastic collision wi9th other body 'Q' of mass 5 kg, which is at rest. What is velocity of Q after collision?
