Bradley dropped a ball from a roof 16feet high. Each time the ball hits the ground it bounces 3/5 the previous height. Find the height ball will bounce after hitting the ground the fourth time

Answers

Answer:

The ball will bounce to 2.07 feet after 4th drop.

Step-by-step explanation:

Bradley dropped a ball from a roof 16 feet high. So, its the initial height.

Each time the ball hits the ground it bounces 3/5 the previous height.

Means after 1st drop, the ball will again rise to (3)/(5)*16= 9.6 feet.

Similarly after 2nd drop, it will bounce to  (3)/(5)*9.6=5.76

After 3rd drop, it will bounce to (3)/(5)*5.76=3.456 feet

After 4th drop, it will bounce to (3)/(5)*3.456=2.0736 feet

Hence, the ball will bounce to 2.07 feet after 4th drop.

Answer: 2.0736 ft

Step-by-step explanation:

Bounce 1: 16*3/5=9.6

Bounce 2: 9.6*3/5=5.76

Bounce 3: 5.76*3/5=3.456

Bounce 4: 3.456*3/5=2.0736
