Any idea how to solve this problem?
soldier1979 [14.2K]

Step-by-step explanation:

h(t) = -5t^{2} + 15t

To determine the time it takes for the ball to hit the ground, we need to figure out when h(t) = 0.

0 = -5t^{2} + 15t

t^{2} - 3t = 0

t(t - 3) = 0

Separating this into two separate equations will give us the times that h(t) = 0:

t = 0

t - 3 = 0

t = 3

We can ignore t = 0 since that is the initial time that the ball is kicked from the ground, so the answer to the question is t = 3.
