Long word problem, bare with me

julian kicked a soccer ball into the air with an initial upward velocity of 40 feet per second. the height (h) in feet of the ball above the ground can be modeled by h= -16t^2+40t, where (t) is the time in seconds after julian kicked the ball. find the time in takes the ball to return to the ground. hint: factor and then solve for (t).

a: 2/5s

b: 1 and 1/3s

c 1 and 3/4s

d 2 and 1/2s

5/2 seconds

Step-by-step explanation:

The ball will return to the ground when the height is 0. So we set the height function to 0 and solve for t.

t is 5/2 seconds. This is when the ball returns to the ground.

Note: I believe it should be answer choice A and there is a mistake in the answer

answer: y=4000x+14000
