- A 1580 kg rocket is to be launched with an initial upward speed of 59.0 m/s. In order to assist its engines, the engineers will start it from rest on a ramp that rises 53° above the horizontal (Figure 1). 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. Figure Rocket starts here. 53° < 1 of 1 Rocket is. -launched upward. Part A How far from the base of the ramp should the rocket start, as measured along the surface of the ramp?
