SUMMARY
The average power of a car can be calculated using the formula for power, which is Work divided by time. In this case, the mass of the car is 2000 kg, and it accelerates from 0 to 120 km/h in 3.5 seconds. To find the force, one must use the formula F=ma, where 'a' is the acceleration derived from the change in velocity over time. Utilizing the work-energy theorem simplifies the calculation by relating work done to kinetic energy without assuming constant acceleration.
