2) Figure 3 illustrates a first block having mass M1 positioned on a horizontal tabletop. The contacting surfaces between the 1st block and the tabletop have a coefficient of kinetic friction Uk. An ideal rope extends horizontally from the 1st block to an ideal pulley and then vertically downward to a 2nd block having mass M2. Initially, the 2nd block is traveling downward with speed Vo. At some later time, the 2nd block has been displaced a distance H and its speed is Vf. Rope Pulley M, Friction M, Figure 3 Determine expressions {M1, M2, Hk, H, g, Vo} for the following: H (a) Work done by gravity onto the system of 2 blocks; (b) Work done by the normal force onto the system of 2 blocks; (c) Work done by tension onto the system of 2 blocks; and (d) final speed, Vf.

A block of 1:6 kg mass is on a plane inclined to 50 for which the kinetic friction coecient is c = 0:12. The block is connected to a spring of constant k = 5 N=m by a string. The latter passes without slipping through a pulley which is assimilated to a 1 kg disc having a radius of 0:15 m. If the system is initially at rest and the spring has a zero elongation, what is the module of the speed of the block when it has slipped by 0:Five feet down the incline?
Two blocks with masses m1 = 5.0 kg and m2 = 7.0 kg are attached by a string as shown in the figure below, over a pulley with mass M = 2.0 kg. The blocks are released from rest. The pulley, which turns on a frictionless axle, is a hollow cylinder with radius 0.050 m over which the string moves without slipping. The horizontal surface is frictionless. Find the speed of the system when the block of mass m2 has dropped 2 m.
A block of mass m= 2.0 kg is released from rest on an inclined plane at a height of h = 1.5 m.
