Concept

Problem: A 1560 kg rocket is to be launched with an initial upward speed of 53.0 m/s . In order to assist its engines, the engineers will start it from rest on a ramp that rises 53 above the horizontal (the figure ). At the bottom, the ramp turns upward and launches the rocket vertically. The engines provide a constant forward thrust of 2000 N, and friction with the ramp surface is a constant 500 N.How far from the base of the ramp should the rocket start, as measured along the surface of the ramp?
