Your niece has asked you to take her sledding. Your niece and the sled have a combined mass of 30 kg, and the coefficients of friction between the sled and the snow are μ_s=0.19 and μ_k=0.06. Assuming you get a running start at the hill, with what force do you need to pull on the sled (parallel to the slope) to maintain constant velocity up the hill? Draw and label your free body diagram and sum your forces to solve for F

Two blocks, A and B, are connected by a rope. A second rope is connected to block B and a steady, horizontal tension force of T=50 Newtons is applied. The system moves at a constant speed across the ground. Block B experiences a friction force of 10 Newtons. A.Draw and label an appropriate force vector diagram for block B.  B.What is the friction force acting on block A?

Block 1 (10 kg) is located on the surface of a table. A rope pulls on block 1 with a horizontal tension of 58 N to the right and a vertical tension of 60N upward. The coefficient of kinetic friction between the block and the surface equals 0.2. On a sheet of paper, draw the free body diagram for block 1 using the two- subscript notation from class. After completing the free body diagram, enter below each force and its x & y-components. Remember that the x-component is the "i" component and the y-component is the "j" component.

You want to use a rope to pull a 12-kg box of books up a plane inclined 30° above the horizontal. The coefficient of kinetic friction is 0.28. The rope pulls parallel to the incline. Part A What force do you need to exert on the rope if you want to pull the box at constant speed. Express your answer with the appropriate units.
