At time t=0, a ball is thrown downward at 24 feet per second from a height of 160 feet above the ground. The equation h = -16t^2 - 24t +160 describes the height (in feet) of the ball. In how many seconds will the ball hit the ground?

Respuesta :

Answer:

After 2.5 seconds.

Step-by-step explanation:

The function represents the height of the ball. So when it hits the ground, the height of the ball is 0. You set h = 0 and solve for t. Once you do that, you get t = -4, 2.5. However, time can't be negative so only 2.5 seconds is an answer
