A block is allowed to slide down a ramp of length L until it reaches the bottom. The coefficient of kinetic friction between the block and the ramp is μk > 0. If the experiment is carried out with the ramp at an angle of θ = 30∘, 45∘, and 60∘ to the horizontal, in which case does the force of friction do the most work?

A block of mass m = 0.1 kg falls down a ramp of height h = 0.5 m and angle θ = 30 degrees. The coefficient of kinetic friction between the block and the ramp is given by μ, which will vary throughout this problem. At the end of the ramp, the block slides along a frictionless horizontal surface until it makes contact with, and compresses, a mass-less spring with spring constant k = 1.0 N/m. Assume g = 9.81 m/s2. Determine the following:Assume the ramp is frictionless (i. e., μ = 0). What is the maximum distance that the spring will compress? What coefficient of kinetic friction, μ, will cause the spring to compress by exactly half the distance that it did when the ramp was frictionless? Using the value of the coefficient of friction found in part 2, when the spring pushes the block back towards the ramp, what is the maximum height that the block reaches?

A block of mass m = 4.00 kg, starting from rest, slides down a frictionless inclined plane (ramp) of length 3.00 m. The plane is inclined by an angle of θ = 25.0∘ to the ground. At the bottom of the plane, the block slides along a rough horizontal surface with a coefficient of kinetic friction μk = 0.200 until it comes to rest. Let y = 0 represent a position along this horizontal surface. a) What is the initial mechanical energy (kinetic plus potential) of the object? b) What is the speed of the block when it reaches the bottom of the ramp? c) What is the work done by the friction force? d) What is the magnitude of the friction force on the horizontal surface? e) How far does the object slide along the horizontal surface before stopping?
