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 110 kg, and the coefficient of kinetic friction between the road and him is 0.825. Find the tension in the cable.

Answer 1

The cable tension T equals the friction force, since there is zero acceleration.

T = M*g*(0.825) = 889 Newtons

That's about 200 pounds
