Answer:
2.11 sec
Step-by-step explanation:
Given that the ball is thrown from a height of 80 feet
it follows the equation
when the ball hits the ground the height if the ball is equal to 0
7 = a/2 + 4
first subtract 4 from both sides
7 (-4) = a/2 +4 (-4)
3 = a/2
Then isolate a by multiplying 2 to both sides
3(2) = a/2 x 2
6 = a
a = 6
hope this helps
