A 1700 kg car starts from rest at position A and accelerates uniformly up the incline, reaching a speed of 100 km/h at position B. Determine the power required just before the car reaches position B and also the power required when the car is halfway between positions A and B. Calculate the net tractive force F required. answer should be at B: P = 193.4 kW, halfway: P= 136.7 kW, F= 6960N.
