A 239-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 29.0° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.800, and the log has an acceleration of 0.900 m/s2. Find the tension in the rope.
