A car travels in a straight line up a slope, as shown in [Figure 3.1]. The car has mass 850 kg and travels with a constant speed of 9.0 m s⁻¹. The car's engine exerts a force on the car of 2.0 kN up the slope. A resistive force FD, due to friction and air resistance, opposes the motion of the car. The variation of FD with the speed v of the car is shown in [Figure 3.2].
