Hello. I need some help with the following problem.(adsbygoogle = window.adsbygoogle || []).push({});

There is a cart on an incline and a pulley with a suspended block.

Assuming that (the force of friction)= (mu)(N) symbolically show that the coefficient of rolling friction for the car moving down the incline plane with a constant speed is given by mu = tan(theta) - m/[(M*cos(theta))]

M is the mass of the car and

m is the mass of the suspended weight over the incline

Any help would be appreciated

Thanks
