                A model rocket is launched straight upward with an initial speed of 50m/s. It acccelerates with a constant upward acceleration of 2m/s^2 until its engines stop at an altitude of 150m. (a)What is the maximum height reached by the rocket? (b)How long after lift-off does the rocket reach its maximum height? (c) How long is the rocket in the air?

    a) find the velocicy due to the acceleration at the shutoff  h=150m. Using that velocity, find the max height (when vfinal=0).
b)how long does it take to reach 150m? Then, how much longer to the top?
