A car of mass 960kg is free-wheeling down an incline at a constant speed of 9.0 m/s. The slope makes an angle of 15 degrees. Deduce that the average resistive force acting on the car is 2.4*10^3 N.

Question

what resistive force?

anonymous · Answer

If the car is travelling at a constant speed, then the resistive force must be equal to the pulling force. The pulling force is gravity, which acts downward, and accelerates the car down the slope.
