A 1400 kg car travels up a 20 degrees incline. The car exerts a constant force of 30,000 N across 100m. The car starts from rest at the bottom of the incline. The car takes 10 minutes to do this. How much work is done by the car?

Answer 1

I do not understand what the 30,000 N force is doing, is that in the direction of movement?

If it is, then work done = 10,000*100 Joules

Answer 2

A 1400 kg car accelerates from rest to 95 km/hr in 7.4 sec. Whatb is the average power delivered by the engine?
