Question 931460
if a ball is thrown vertically up from the ground, its height h after t seconds is given by h(t)=96t-16t^2
A. how long does it take the ball to return the ground.
96t-16t^2 = 0
Solve for t.
========================
B. how long does it take the ball to pass through a height of 80ft on the way back down>
96t-16t^2 = 80
Solve for t.
