A 211 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 0.850, and the log has an acceleration of 0.700 m/s2. Find the tension in the rope.

T-(211 * 10 * sin30)-(.85 * 211 * 10 * cos30) = 211 * .7

Solve this eqn to get the answer
T is tension and * means multiplication
