1. The problem statement, all variables and given/known data The (non-conservative) force propelling a 1.10 x 10(3)-kg car up a mountain road does 6.80 x 10(6) J of work on the car. The car starts from rest at sea level and has a speed of 22.0 m/s at an altitude of 1.90 x 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. Calculate the work done by non-conservative forces using Wnc = dKE +DPE where Wnc= W friction+W air+W engine 2. Relevant equations I used W1= .5MV2 + MGH and required W =W1-W 3. The attempt at a solution .5*1100kg*(22squared m/s) + 1100kg*9.8*192m = 2335960J 2335960-6800000 = -1655960J What did I do wrong?
