An asteroid is moving along a straight line. A force acts alongthe displacement of the asteroid and slows it down. The asteroidhas a mass of 5.0×104 kg, and theforce causes its speed to change from 7800 to 4500m/s. (a) What is the work done by theforce? (b) If the asteroid slows down over adistance of 2×106 m determine themagnitude of the force.
