model rocket is launched straight upward with an initial speed of 50.0 m/s. It accelerates with a constant upward acceleration of 1.00 m/s2 until its engines stop at an altitude of 130 m.
(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?
Follow the approach outlined in this similar question of a few days ago:
A certain car is capable of accelerating at a rate of +0.60 m/s2. How long does it take for this car to go from a speed of 20 mi/h to a speed of 65 mi/h?
idk whats the answer
