Question: the nonconservative force propelling a 110 x 103kg car up...

The (non-conservative) force propelling a 1.10 x 10³-kg car up a mountain road does 6.50 x 10⁶ J of work on the car. The car starts from rest at sea level and has a speed of 20.0 m/s at an altitude of 1.60 x 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.
