Physics: Magnitude of Force?

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 4.8 × 104 kg, and the force causes its speed to change from 6600 to 4600 m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.8 ×... show more 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 4.8 × 104 kg, and the force causes its speed to change from 6600 to 4600 m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.8 × 106 m determine the magnitude of the force.
