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!
Natalie


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
