Answer:
Step-by-step explanation:
If we are looking for v, the equation is
[tex]y=-16x^2+vt[/tex], assuming that the ball was on the ground before it was kicked. If it takes 2 seconds to hit the ground after being kicked, we replace y with 0 since the height of something on the ground has no height at all. We also replace x with 2, since it takes 2 seconds for the ball to be at the height of 0:
[tex]0=-16(2)^2+v(2)[/tex] and
0 = -64 + 2v and
-2v = -64 so
v = 32 feet per second
