From physics we know that the distance a ball falls is
s = (g/2) t² = 4.9 t² meters,
thus,
h1 = 4.9 t² so t = (h1/4.9)½
.
(We are using g = 9.8 m/s² and ignoring air
friction, which is minimal for small heights.)
We just saw the relation of each bounce height to the first bounce height; now we will see that the time of each bounce time is related to the time of the first bounce. claim that the time for the second bounce is will now calculate the total time from the first instant the ball hits the floor:
