The height, h, in feet of a gold ball above the ground after being hit into the air is given by the equation. h=-16t2+64t, where t is the number of seconds elapsed since the ball was hit. how many seconds does it take for the golf ball to hit the ground?

4 seconds

Step-by-step explanation:

Given :

To Find: How many seconds does it take for the golf ball to hit the ground?

Solution :

Since we are given an equation :

Where H denotes height

t denotes the number of seconds elapsed since the ball was hit.

When he golf ball to hit the ground at that time the height becomes 0

So, put H = 0 in the equation

Thus it take 4 seconds for the golf ball to hit the ground

the answer is c)8
