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.

after how many seconds does the ball hit the ground? that means h = 0
rt - 16t^2 = 0
r - initial speed
OpenStudy (bahrom7893):
So:
96t - 16t^2 = 0
16(6t - t^2) = 0
OpenStudy (bahrom7893):
6t-t^2 = 0
t(6-t)=0
t = 0
or t = 6

Is he in the major leagues or minors.

is the answer.. since t = 0 is initial value

Well after at least 0 seconds, because it is impossible to have a negative time.. unless you go with time travel o.O
OpenStudy (bahrom7893):
t = 6 is the answer i meant
