A stuntman is being pulled along a rough road at a constant velocity, by a cable attached to a moving truck. The cable is parallel to the ground. The mass of the stuntman is 109 kg, and the coefficient of kinetic friction between the road and him is 0.87 . Find the tension in the cable.
The friction force between the stuntman and the road is:
f = weight of the ...
