Yes what I meant is that it decreased 1/4 of every its impact, so therefore the answer would be 60 mph after first impact.
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 one-fourth 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...
