Compute the amount of work done on the rocket by the engine

Reference no: EM13660703

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.
