An asteroid is moving along a straight line. a force acts along the displacement of the asteroid and slows it down. the asteroid has a mass of 3.5× 104 kg, and the force causes its speed to change from 6600 to 5700m/s. (a) what is the work done by the force? (b) if the asteroid slows down over a distance of 1.5× 106 m determine the magnitude of the force.
