Question

A batter hits a baseball upward with an initial speed of 96 feet per second. After how many seconds does the ball hit the ground? Use the formula h = rt − 16t2 where h represents height in feet and r represents the initial speed

Answer 1

h = 96t - 16t^2
as the ball ends up on the ground h = 0
96t - 16t^2 = 0
16t(6 - t) = 0
t = 6 seconds
