A 1530 kg rocket is to be launched with an initial upward speed of54.0 m/s. In order to assist its engines, the engineers will startit from rest on a ramp that rises 53 ^\circ above the horizontal. At the bottom, the ramp turnsupward and launches the rocket vertically. The engines provide aconstant forward thrust of 2000 {\rm N}, and friction with the ramp surface is a constant500 {\rm N}.
How far from the base of the ramp should therocket start, as measured along the surface of the ramp?
