The coefficient of kinetic friction between the block and the ramp is 0.20. If the distance for the to reach the top of the ramp or the bottom of the ramp are both 10 m, how long will it reach the top or bottom of the ramp after the setup is released? Note the pulley is massless, therefore the tension in the rope in the problem is the same at both sides of the pulley. Angle is 30 degrees, box on the left is 10kg and box hanging on the right is 5 kg.
