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.
