A small block sits at one end of a flat board that is 4.00 m long. The coefficients of friction between the block and the board are μs= 0.450 and μ = 0.400. The end of the board where the block sits is slowly raised until the angle the board makes with the horizontal is α0, and then the block starts to slide down the board. If the angle is kept equal to α0 as the block slides, what is the speed of the block when it reaches the bottom of the board? Express your answer with the appropriate units.

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?
A 10 kg box is being pushed across a rough surface with a constant speed of 2 m/s. The person pushing the box slips and stops pushing. The box continues to slide across the surface before coming to rest. If the coefficient of friction between the crate and the surface is 0.1, how far does the box travel before coming to rest?
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 2.0 kg piece of wood slides on a curved surface . The sides of the surface are perfectly smooth, but the rough horizontal bottom is 30 m long and has a kinetic friction coefficient of 0.20 with the wood. The piece of wood starts from rest 4.0 m above the rough bottom. (a) Where will this wood eventually come to rest? (b) For the motion from the initial release until the piece of wood comes to rest, what is the total amount of work done by friction?
An object with mass m = 34 kg is pushed with 452 N of force to be moved across a distance of 4.6 m on a surface with friction. Initially the object is moving at vi = 0.82 m/s and after being moved across 4.6 m, the final speed is 2.5 m/s. What is the magnitude of the frictional force acting on the object in the unit of N?
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.

A block of mass m =2.2 kg slides on the ground. At the start of the slide, the velocity of the block is v = 3.1 m/s. Then the block comes to rest. We observe that the block slides for s =2.7 m before coming to rest. Assuming that only kinetic friction force acts on the lock when we observe the motion, what is the kinetic friction coefficient between the block and the ground?
The 2.0 kg block in the figure slides down a frictionless curved ramp, starting from rest at a height of h = 3.60 m. The block then slides d = 7.60 m on a rough horizontal surface before coming to rest. What is the coefficient of friction between the block and the horizontal surface? m = 2 kg
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?
