Question

A rubber ball is dropped from a height of 25 m. which strikes the ground and rebound everytimes to the half of height from where it is fall down. what os the total distance travelled by the ball to come that rest position?​

Answer 1

Answer:

D=287.5m

The ball bounces 4 times then comes to rest

h=25m

(e^2)^n=h1/h

e^2=4th root(12.5/25)

e^2=0.84

D=h[(1+e^2)/(1-e^2)]

D=25(1+0.84/1-0.84)

D=25(1.84/0.16)

D=25(11.5)

D=287.5m
