A baseball is thrown from a stadium seat and its path is shown by h(t)=-16t^2+75, where h is height in feet and t is time in seconds.
A. How long before the ball hits the ground. Round to hundredths
h(t)=-16t^2+75
It hits the ground when h(t) = 0
-16t^2+75 = 0
Solve for t
===============================
B. How high off the ground is the stadium seat?
h(t) at t = 0
