A 216-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 32.5° with respect to the horizontal. The coefficient of kinetic friction between the log and the ramp is 0.758, and the log has anacceleration of 0.698 m/s². Find the tension in the rope.
