Question

A metal ball falls from a height of 32meter on a steel plate.if the coefficient of restitution is 0.5 to what height will the ball rise after second bounce

Answer 1

For an object bouncing off a stationary object, such as a floor, coefficient of restitution,

e=hH−−√⇒h=e2H=0.25×32=8me=hH⇒h=e2H=0.25×32=8m

Answer 2

Answer:

h(n) = h.e^2n

h(2nd rebound so n=2) = 34(0.5)^4

h(n) = 2m
