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. ...?
ht = 96 t - 16t^2
96t - 16t^2 = 0 (divide all with 16)
6t - t^2 = 0
t (t-6) = 0
t = 6
Hope this helps
