The equation for a projectile's height versus time is h(t)=-16t^2+Vt+h. A tennis ball machine serves a ball vertically into the

air from a height of 2 feet, with an initial speed of 130 feet per second. Which equation correctly models the ball's height as a function of time?

Answer:

h (t) = - 16t ^ 2 + 130t + 2

This answer is correct, there is a question on apex with the same equation but it is 110t, the answer to that is.

h (t) = - 16t ^ 2 + 110t + 2

For this case we must use the projectile equation for this problem.
We have then:
h (t) = - 16t ^ 2 + Vt + h
Where,
V: initial speed
h: height
For the tennis ball we have:
h (t) = - 16t ^ 2 + 130t + 2
Answer:
An equation that correctly models the ball's height as a function of time is:
h (t) = - 16t ^ 2 + 130t + 2
