A test rocket is fired perpendicularly upwards. It has a mass of 4.5 x104 kg and its engine can apply a force of 8.5 x107 N. The rocket is designed in such a way that the rocket fires until it reaches a height of 2.4 km.
Compute the amount of work done on the rocket by the engine.
Describe why, in this case, the amount of work done by the engine is not equal to the kinetic energy of the rocket.
Compute the potential energy of the rocket when the engine shuts down.
Use your answers from parts (a) and (c) to help you compute the kinetic energy of the rocket when the engine shuts down. suppose that g = 9.8N/kg
The rocket will continue to climb after its engine shuts down. Compute the maximum height reached by the rocket.
