A ball bounces back 0.6 of it’s height on every bounce. If a ball is dropped from 200 feet, how high does it bounce on the fifth bounce? Round to the nearest tenth.
Accepted Solution
A:
To calculate how high the ball bounces on the fifth bounce, we can use the given information that the ball bounces back 0.6 (60%) of its height on each bounce.
Let's break down the bounces:
1st bounce: The ball is dropped from 200 feet.
2nd bounce: The ball bounces back 0.6 times its height from the 1st bounce.
3rd bounce: The ball bounces back 0.6 times its height from the 2nd bounce.
4th bounce: The ball bounces back 0.6 times its height from the 3rd bounce.
5th bounce: The ball bounces back 0.6 times its height from the 4th bounce.
Let's calculate the heights for each bounce:
$$1st \:bounce: 200 feet$$
$$2nd \:bounce: 0.6 \times 200 feet = 120 feet$$
$$3rd \:bounce: 0.6 \times 120 feet = 72 feet$$
$$4th \:bounce: 0.6 \times 72 feet = 43.2 feet$$
$$5th \:bounce: 0.6 \times 43.2 feet = 25.92 feet$$
Rounding to the nearest tenth, the ball bounces to approximately 25.9 feet on the fifth bounce.
