Final answer:
The answer discusses the force needed to stop a car, whether this force does work, and where the kinetic energy goes when a car stops.
Explanation:
(a) The magnitude of the average force acting on the car can be calculated using the formula F=ma. If the car has a mass of 1,800 kg and it stops, the force exerted would be influenced by the rate of deceleration.
(b) The force found in (a) does work on the car as work is done when a force causes displacement. In this case, the force causes the car to stop, so work is done in stopping its motion.
(c) The net change in the car's kinetic energy is zero as the car goes from moving at a certain speed to being at rest. The kinetic energy lost by the car goes into other forms of energy like heat, sound, and deformation of the car and the tree it hit.
