SUMMARY
The average force exerted by a car due to air resistance can be calculated using the formula Power = Force × Velocity. In this discussion, a car generating 15,000W of power while traveling at a constant speed of 80 km/h requires the calculation of average force. By rearranging the formula, the average force can be determined as Force = Power / Velocity. This results in an average force of 187.5 N when converting 80 km/h to meters per second.
