A stuntman is being pulled along a rough road at a constant velocity by a cable attached to a moving truck. The cable is paralle

l to the ground. The mass of the stuntman is 112 kg, and the coefficient of kinetic friction between the road and him is 0.876. Find the tension in the cable.

Answer:

T = 1633N

Explanation:

The weight of the man is given by m×g =112×9.8= 1097.6N

Coefficient of Kinetic Friction = frictional force / Normal reaction ( Weight of object)

The coefficient of Kinetic Friction= Tan A

Where A is the angle of inclination

The angle of inclination is Tan^-1{0.876} = 41.21°

By identity sin A = Opposite( weight)/ hypothenus ( Tension)

Hence the tension is T = 1097.6/sin 41.21 =

T = 1633N
