Question

A 1000kg weather rocket is launched straight up. The rocketmotor provides a constant acceleration for 16s then the motorstops. The rocket altitude 20s after launch is 5100m. Airresistance is negligible. a) What's the rocket's acceleration after the first 16seconds? b) What's the rocket's speed as it passes through a cloud5100m above the ground.
