Question
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?

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