Answer:
Step-by-step explanation:
GIVEN: A rubber ball dropped on a hard surface takes a sequence of bounces, each one 
as high as the preceding one.
TO FIND: If this ball is dropped from a height of 
feet, how far will it have traveled when it hits the surface the fifth time.
SOLUTION:
once the ball is dropped on hard surface it bounces of preceding one and comes down the same distance.
When the ball is dropped from feet height
after first hit 
new height 
after second hit 
new height 
after third hit 
new height 
after fourth hit 
adding all distance 
feet
Hence the ball will travel 
feet before it hits the surface fifth time.
