stiv31 [10]

Answer:

4 seconds

Step-by-step explanation:

Given : H = -16t^{2} +64t

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

Solution :

Since we are given an equation : H = -16t^{2} +64t

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

H = - 16t^{2} +64t

0 = - 16t^{2} +64t

16t^{2} = 64t

16t = 64

t =\frac{64}{16}

t =4

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