If we look at the free body daram (FBD) for a rocket touch, we see that there are two forces. One is a thrust and the other is the force of gravity dim We can deliver the thrust as a change in de times the relative speed of the partietes creating the thrust . Let the change in mais be a constant, as he often the case with solid fuels. Write the thrust Pa a function of the burnte Assume that the rocket is moving in one direction so that Hint Submit
