Question: A stomp rocket is launched vertically upwards with a burst of air, when a child jumps on a flexible pillow connected to the launcher tube.

A stomp rocket is launched vertically upwards with a burst of air, when a child jumps on a flexible pillow connected to the launcher tube. Air resistance can be ignored in this question. At t=0, the rocket has just left the launcher, it has a speed of 29 m/s and the only force that it experiences is the force of gravity. "Up" is defined as the positive direction and define zero altitude as the position of the rocket at t=0.
