Question: You try to pull a 400-N crate along a horizontal surface by tying a rope around it and pulling upward on the rope at an angle of 30° above the horizontal. Knowing that the force you have to exert on the rope to keep the crate moving with constant velocity is 188 N.

a/ Draw the free body diagram and compute the coefficient of kinetic friction between the crate and the surface.

b/ Is this easier or harder than pulling horizontally? Why?

You are using a rope to pull a 15 kg suitcase along a level path. There is friction between the suitcase and the floor, so you must pull with some difficulty to get the suitcase moving, needing a force of about 120N. Afterward, you find that by maintaining that force, the suitcase acceleration while sliding along the floor, the coefficient of static friction is 0.81and the coefficient of kinetic friction is 0.40. a. Draw a force diagram and label all...

Jack and Zack are standing on a crate at rest on a frictionless horizontal surface. Jack has a mass of 70 kg, Zack has a mass of 45 kg, and the crate has a mass of 15 kg. In what follows, we will see that both jump of the crate. You may assume that they push themselves off with a speed of 4 m/s relative to the crate and in a direction that is essentially horizontal. 1) what is the...

A 336-kg crate rests on a surface that is inclined above the horizontal at an angle of 17.2°. A horizontal force (magnitude = 405 N and parallel to the ground, not the incline) is required to start the crate moving down the incline. What is the coefficient of static friction between the crate and the incline?

You are pushing a set of blocks along a frictionless horizontal surface. The blocks are arranged in order by the 1kg block, then the 2kg block, and then the 3kg block; you push the 1kg block. a. Calculate the force exerted by the 3kg block on the 2kg block. b. Calculate the force exerted by the 2kg block on the 1kg block. For both parts show if you are using Newton's 2nd or 3rd Law and where.

A rope exerts an 18-N force while lowering a 20-kg crate down a plane inclined at 20∘ (the rope is parallel to the plane). A 24-N friction force opposes the motion. The crate starts at rest and moves 11 m down the plane. Part A: Determine the final speed of the crate. The system consists of the crate, the surface of the incline and Earth. Part B: Determine the change in gravitational energy. Part C: Determine the change in kinetic energy....
