Question

Q.33.- What do you mean by elastic and inelastic collision? In case of perfectly elastic collision in one
dimension derive an expression for final velocity of colliding bodies.
A person starts from the centre of a circular track of radius 1.0 km, along one diametrical path and
reaches the circular track. Then walks along one quarter of the track and then along another
diametrical path to reach the centre of the track (A) what is his displacement? (B) What is the path
length?​

Answer 1

Answer:

what is elastic collision

An elastic collision is an encounter between two bodies in which the total kinetic energy of the two bodies remains the same. Basically, in the case of collision, the kinetic energy before the collision and after the collision remains the same and is not converted to any other form of energy.
