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?

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.

An initially stationary block of mass m = 5.0 kg is attached to a relaxed spring with a spring constant K = 16 N/m on a rough plane inclined at an angle θ (with cos⁡θ = 0.8 and sin⁡θ = 0.6). The coefficient of kinetic friction between the block and the plane is μk = 0.40. A vertically downward uniform force F = 240 N acts on the block as it moves from A to B a distance d = 2.5 m down the plane. During this descent from A to B , calculate the amount of work done on the block by: a) the normal force, b) the gravitational force, c) the spring force, d) the force F , and e ) the force of kinetic friction. f) Deduce the kinetic energy and the speed of m as it passes through point B.
