A 400g model rocket is on a cart that is rolling to the right at a speed of 4.0m/s. The rocket engine, when it is fired, exerts an 7.0 N thrust on the rocket. Your goal is to have the rocket pass through a small horizontal hoop that is 15m above the launch point.

Answer Wiki. To get to an approximately circular low earth orbit and stay there, a rocket needs to accelerate whatever vehicle it is delivering into space up to about 8 km per second relative to the earth. Of course, the rocket starts at a speed of 0 (right at liftoff) and accelerates rapidly to reach that speed, discarding stages along the way.
