23 The following diagram shows a car rolling down a slope. The car has a mass of 1.2  10 3 kg and the slope is at 15  to the horizontal. The acceleration due to gravity is 10 m s  2. 18 On the diagram mark in the forces acting on the car.

24 If the total resistance force acting on the car has a magnitude of 1000 N, calculate the acceleration of the car. 19
