The height reached by a model rocket can be calculated using the equation h = -1672 + vt + where t is the time the rocket is in flight, v is the rocket's velocity, and n is the rocket's beginning
height.
Calculate the height, h, at 3 seconds given that the rocket travels 85 feet per second and starts on a
launch pad 15 feet off the ground.
Knowns:
t = 3 seconds
v=85 feet per second
n = 15 feet
If we plug all those values in, our formula becomes h = = (-16 -34) + (85 . 3) + (15).
Solve for h
The height of the rocket at 3 seconds is
feet.
