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 5.60 104 kg, and the force causes its speed to change from 7300 to 5400 m/s.
(a) What is the work done by the force?
Work =
(b) If the asteroid slows down over a distance of 2.00 106 m, determine the magnitude of the force.
F =
