Brice · Answer 1

In the question where as a model rocket is launched straight upward with an initial speed of 50.0m/s and it accelerate with a constant acceleration of 2m/s^2 until it engines stop at an altitude od 150. So the following are the answer to your question:

a. The motion, the acceleration was equals to Zero

b. the maximum height is 150m
