A box of mass m = 9.00 kg is located at the top of a ramp of height h = 7.00 m, as shown in the figure. The coefficient of kinetic friction between the ramp and the box is μk = 0.6. You give the box a push so that it starts sliding down with an initial speed of 2.50 m/s. The box continues its motion on a rough horizontal surface for 15.00 m until it hits a spring of spring constant k = 300. N/m and fully compresses it by 50.0 cm before coming to rest. What is the coefficient of kinetic friction between the horizontal surface and the box?

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?

Starting from rest, a small block of mass m = 0.25 kg slides down an incline from a height h = 1.2 m. As it slides down, the block experiences a force of kinetic friction of constant magnitude fk = 2.1 N only over a distance L = 0.2 m, as shown in the figure. The incline is frictionless everywhere else. After reaching the bottom of the incline, the block strikes a larger block of mass M = 1.8 kg that is attached to a spring of spring constant k = 6.5 N/m. The large block was originally at rest. The blocks stick together upon impact and travel together on the frictionless horizontal surface. Assume that both blocks are subject to the regular force of gravity (g = 9.80665 m/s2). (a) Determine the speed of the small block right before it collides with the larger block. Answer: m/s (b) Determine the speed of the combination of the two blocks immediately after the collision. Answer: m/s (c) Determine the compression of the spring when the combination of the two blocks comes to rest. Answer: m

Work. A block of mass m = 2.00 kg is attached to a spring of force constant k = 500 N/m as shown on the right. The block is pulled to a position xi = 5.00 cm to the right of equilibrium and released from rest. There is friction between the surface and the block. The coefficient of friction between block and surface is μk = 0.350. (a) (3 pts) What is the work done by the elastic force during the displacement? (b) (2 pts) What is the work done by the kinetic friction on the block during its motion? (2 pts) (d) (5 pts) What is the speed of the block as it passes through the equilibrium position? Use work-kinetic energy theorem.
