Q:
# 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

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
