A spacecraft in deep space is isolated from its surroundings and is initially moving with the velocity v shown in the diagram above. It has thrusters on a swivel that fire such that the spacecraft experiences three possible forces that act at fixed angles relative to the velocity vector of the spacecraft. With each of the forces separately with a steady magnitude, what initially happens to the kinetic energy K, of the spacecraft?
