287 9.29 Calculate the change in the momentum of a car whose speed changes from 100 km/h to 20 km/h. The car has a mass of 1000 kg and is moving along a straight line. Express your answer in SI, BG, and U.S. Customary units.
A car accelerates from rest along a straight road, increasing its momentum from 0 to 52500 kg-m/s in 6.5 s. If its engine and tires are able to provide an average force of 8500 N, what is the magnitude of the net dissipative force (friction and air resistance) on the car during this interval?
