A 1000 kg weather rocket is launched straight up.The rocket motor provides a constant acceleration for 16 s, then the motor stop
s. The rocket altitude 20 s after launch is 5100 m. You can ignore any effects of air resistance. What is the rocket's speed as it passes through a cloud 5100 m above the ground? Not sure what i'm doing.
If there are no forces acting upon the object, then there is no acceleration. If there is no acceleration, then the object will move with a constant velocity.
