The (non-conservative) force propelling 1.50*10^ 3 -kg a car up a mountain road does 4.70 * 10 ^ 6 * 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 * 10 ^ 2 * 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
