A 287-kg log is pulled up a ramp by means of a rope that is parallel to the surface of the ramp. The ramp is inclined at 30.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.810, and the log has an acceleration of 0.900 m/s2. Find the tension in the rope.

    Tension= friction+ma-gravity down the ramp
    tension= mu*mg*cos30+ma-mgsinTheta
