Fay's rubber ball bounces exactly half the height from which it is dropped. She drops the ball from the top of a building that is 64 meters tall. How high will the ball bounce on its eighth bounce.
Could someone explain this?
Thank you!

1/2 of 64= 32.
32 feet is how high it bounces on the 1st bounce
1/2 of 32=16
16 feet is how high it bounces on the 2nd bounce
Need anymore help or can you do the rest by yourself?
8 meters
The nth bounce derives from
B = 64/(2^n)where n == the nth boumce.
the answer is 1/4 meters

a ball dropped to the ground bounces back to 2/3 of its pervious height. if the ball is dropped straight down form a height of 81 cm, how far does it travel altogether by the time it hits the ground for the fitth time?
