Question: A rocket engine is designed to push with a force of 1000 N on a 100 kg mass. Assuming this force and the velocity of this mass are always in the same direction,
Part A: How far must the mass be pushed to reach v/c= 0.25?
I want help to find how far the mass must be pushed to reach v/c= 0.25 and hint- use the work-kinetic energy theorem with work just force times distance.
