Apunter kicks a football upward with an initial speed of 48 feet per second. after how many seconds does the ball hit the ground? use the formula h = rt − 16t2 where h represents height in feet and r represents the initial speed

check the picture below. That's pretty much a rough graph of an initial speed scenario.

so, we know the ball will hit the ground when h = 0, and we know that r = 48, thus

3 seconds.

Step-by-step explanation:

We have been given that a punter kicks a football upward with an initial speed of 48 feet per second. Use the formula to find after how many minutes ball will hit the ground.

The ball will hit the ground, when height, h equals to 0.

Using zero product property, we will get:

Therefore, after 3 seconds ball will hit the ground.

b. 18.25 times two is 36.50
