SUMMARY
The discussion centers on calculating the horizontal resistive force acting on a vehicle traveling at a constant speed of 55 m/s with a useful power output of 22 kW. The formula used is P = FV, leading to the conclusion that the resistive force is 400 N. The participants confirm that at constant speed, the net force is zero, indicating that the driving force equals the resistive force.
