Question

What is elastic collision? Show that in an elastic collision, the relative velocity of approach before collision is equal to relative velocity of separation. Also find the velocity after collision.

Answer 1

Answer:

Work, Energy and Power. Show that in one dimension elastic collision, velocity of separation is equal to the velocity of approach. i.e. relative velocity of approach is equal to relative velocity of separation. Hence the result.

Answer 2

Answer:

Or this can also be said that the relative velocity of approach is equal to the relative velocity of separation. So this is proved that in one dimensional elastic collision of two bodies, the relative velocity of separation after collision is equal to the relative velocity of approach before collision.
