Acertain ball has the property that each time it falls from aheight h onto a hard level surface, it rebounds to aheight rh, where 0 < r < 1. suppose thatthe ball is dropped from an initial height h meters.
a)assuming that the ball continues to bounceindefinitely, find the total distance that it travels. (use the fact thatthe ball falls (1/2)gt2 meters in tseconds)
b)calculate the total time that the balltravels.
c)suppose that each time the ball strikes thesurface with velocity v it rebounds with velocity -kv, where0 < k < 1. how long will it take for the ball tocome to rest?
