Answer:

t = 3 seconds

Explanation:

You can think of this as a quadratic and find the zeros. i will use x and y to make it easier.

y = -16x^2 + 48x

y = (x)(-16x+48)

y = (-16)(x)(x-3)

This means your zeros are at x = 0 and x-3 = 0, so 0 and 3.

0 is when the ball leaves the ground, so 3 is when it returns.
