Question

if a body falls from a height h and strikes the ground with a velocity u and rebounds with a velocity v up to height h1 then
find all these given below
a) the cofficient of restitution e
b) the height reached by the body after n th rebounce hn
c) the speed of the body after n ^ th rebounce Vn
d) Total distance (s) covered by it before coming in rest ​

Answer 1

Answer:

if a body falls from a height

Answer 2

Answer:

When a body falls from height h, it strikes the ground with a velocity v=2gh. Let it rebounce with a velocity v and rise to a weight h1.

v=2gh1

e=vuhh1

Clearly, h1=e2h
