Sharing kicks a ball from the ground into the air with an upward velocity of 64ft per second. The function h=-16t^2+64t models the height h, in feet, of the ball at time t, in seconds. When will the ball reach the ground again.

h = -16t^2 + 64t
When the ball reaches the ground, h will equal zero.
0 = -16t^2 + 64t
16t^2 = 64t
16t = 64
t = 4 seconds
