The (nonconservative) force propelling a 1.50 * 103-kg car up a mountain road does 4.70 * 106 J of work on the car. The car starts from rest at sea level and has a speed of 27.0 m/s at an altitude of 2.00 * 102 m above sea level. Obtain the work done on the car by the combined forces of friction and air resistance, both of which are non conservative forces
