Three rectangular boxes are stacked on top of each other. All the boxes have the same mass of 1.2 kg. The kinetic coefficients of friction between the boxes are all 0.6 and the static coefficient of friction is 0.7. There is no friction between the bottom box and the floor. A rope is attached to the lowest box and pulls on the lowest box with a force of 5.0 N. Suppose the force on the rope is slowly increased. How large can the force be before the boxes begin to slide on each other?

A rope pulls on the lower block in the figure with a force of 46.2 N. The coefficient of kinetic friction between the lower block and the surface is 0.1. The coefficient of kinetic friction between the lower block and the upper block is also 0.1. Consider the pulley/ropes to be massless and frictionless. The upper block's mass is 2.5 kg. The lower block's mass is 4 kg. What is the acceleration of the lower block? Express your answer in m/s2. Your result must contain at least one digit after the decimal point
A 1520-N crate is to be held in place on a ramp that rises at 30.0° above the horizontal (see figure). The massless rope attached to the crate makes a 22.0° angle above the surface of the ramp. The coefficients of friction between the crate and the surface of the ramp are uk = 0.450 and us = 0.650. The pulley has no appreciable mass or friction. What is the MAXIMUM weight w that can be used to hold this crate stationary on the ramp? w = ? Crate 22.0 Ramp 30,0
A box with with a mass m = 2kg is being pushed up a ramp by an unknown pushing force Fp. The coefficient of static friction between the box and interface is 0.7. The coefficient of kinetic friction between the box and interface is 0.6. The incline of the ramp is 15 degrees. The velocity of the box is constant. The surface of the ramp is 12 m. Fp is removed when the box reaches the top of the ramp. What is the acceleratin of the box after Fp is removed?
You are a bully. You pin a 48 kg dweeb to a wall so that his feet aren't touching the ground. Your arm is extended so that it makes an angle 28 degrees with the horizontal. The dweeb's back is so sweaty with fear that there is no friction between his back and the wall. What is the magnitude of the force , in N, you must apply to keep the dweeb in equilibrium? (Use g = 10 m/s2) This scenario is represented schematically below. Unfortunately for you, years later the dweeb is your boss and he makes your life miserable. (Please answer to the fourth decimal place - i.e 12.3445)
A rope pulls on the lower block in the figure with a tension force of 20 N. The coefficient of kinetic friction between the lower block and the surface is 0.16. The coefficient of kinetic friction between the lower block and the upper block is also 0.16. The pulley has no appreciable mass or friction. What is the acceleration of the 2.0 kg block?
A desperate hiker has to think fast to help his friend who has fallen below him. Quickly, he ties a rope to a rock of mass ma and makes his way over the ledge (see the figure). If the coefficient of maximum static friction between the rock and the ground is µ, and the mass of the hiker is mâ, what is the maximum mass of the friend, mc, that the rock can hold so the hikers can then make their way up over the ledge? Assume the rope is parallel to the ground and the point where the rope passes over the ledge is frictionless. mc = Ju
A heavy crate is suspended from two ropes as it is lowered from a high shelf to the floor at a constant speed. One of the ropes makes an angle of 28.2 degrees with respect to the vertical and has a tension of 950 N, while the other makes an angle of 33.7 with respect to the vertical. What is the crate's mass in kg?
A 50-kg box is resting on a horizontal floor. A force of 250 N directed at an angle of 30.0° below the horizontal is applied to the box.
