A car cruises with constant velocity on a (low traffic) freeway at 70 mph (about 31 m/s). Wind resistance opposes the car's motion with a force of 5000 N. Intuitively is the forward force on the car less than 5000N, equal to 5000 N or more than 5000 N. Explain your reasoning.

The car is moving with uniform velocity. Hence there is no acceleration in the car. It indicates that net force on the car is zero. Since force in backward direction is exerted by the wind, to make net force zero, the forward push by the car must be equal to backward force by the wind. In other words

Forward force by car = backward force by wind = 5000 N.
