A model rocket is launched straight upward with an initial speed of 50 m/s. It
accelerates with a constant upward acceleration of 2.0 m/s until its engines
stop at an altitude of 150 m.
(a) Describe the motion of the rocket after its engines stop. [Use everyday
language, as if you’re talking to your grandmother.]
(b) Calculate the maximum height reached by the rocket. [Label all kinematics
charts clearly.]
(c) How much time in total is the rocket in the air? Justify your answer.
