A 216 kg log pulled up a ramp by means of a roe that is parallel to the surface of the ramp. The ramp is inclined at 30 degrees with respect to the horiztonal . The coefficient of kinetic friction between the log and the ramp is .810 and the log has a acceleration of .9m/s squared. Find the tension of the rope.
