Show how to approximate the required work by a Riemann sum. Then express the work as an integral and evaluate it.

A \(0.4 - kg\) model rocket is loaded with \(0.75 kg\) of rocket fuel. After launch, the rocket rises at a constant rate of \(4 m/s\) but the rocket fuel is dissipated at a rate of \(0.15 kg/s\). Find the work done in propelling the rocket \(20 m\) above the ground.
