1. A model rocket is launched from the ground with an initial velocity of 160 ft/sec.
a. How long will it take the rocket to reach its maximum height? Show all work.

Answer 1

Assuming there is only force of gravity acting on rocket we can use the projectile equation
$$ \Large \rm {y = \frac12 a t^2 + v_o t } $$

Answer 2

a = -32 ft/s^2
