A 1000kg weather rocket is launched straight up. The rocket motor provides a constant acceleration for 16s , then the motor stops. The rocket altitude after 20s launch is 4200m . You can ignore any effects of air resistance.
1) What was the rocket's acceleration during the first 16s ?
(in m/s^2)
2) What is the rocket's speed as it passes through a cloud 4200m above the ground?
(in m/s)
