Force*distance=workdone
but distance=1.9E6m
solve for 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 4.9 × 104 kg, and the force causes its speed to change from 7600 to 5400 m/s. (a) What is the work done by the force? (b) If the asteroid slows down over a distance of 1.9 × 106 m determine the magnitude of the force.
i found the work is -7.007E11 but i cant find part b) magnitude of the force
