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?
Accepted Solution
A:
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
