A 100-kg box is pulled by a rope parallel to an incline that is at an angle of 200 with the horizontal. The box is moving with an acceleration of 0.50 m/s2 and the coefficient of kinetic friction between the box and the incline is 0.25. Find the force on the rope.

A man wants to accelerate a child on a sled. The combined mass of the child and the sled is 30.0 kg, and the coefficient of kinetic friction between the snow and the sled is 0.150. In case (1), the man applies a force of 200.0 Newtons at an angle of 30.0˚ below the horizontal. In case (2), he applies the same force at an angle of 30.0˚above the horizontal. What is the acceleration of the sled in each case?

A 42.0 kg box on a horizontal surface is being pulled by a horizontal force F= 110N. If the acceleration of the box is 1.20 m/s^2, what is the coefficient of kinetic friction between the box and the surface?
