A rubber ball is thrown straight down from a height of 244 feet at speed of 80 feet per second. If the ball always rebounds with onefourth of its impact speed, what will be the speed of the ball the third time it hits the ground?
My Answer is:
1/4*80=60
1/4*60=45
1/4*45=33.75
1/4*33.75=25.31 for the speed
Or I need to use some kind of formula? Please help me.
