Consider blocks m1 and m2, with m1 held at rest on a horizontal table (where the coefficient of kinetic friction between m1 and the table is μk ), and m2 held in place by a movable, massless, frictionless pulley to which it is attached via a massless cable. As shown in Figure 7, the rope attaching m1 is run across a massless, frictionless pulley affixed to the table, which is then threaded through the movable pulley to then attach to the ceiling. The system is released, and the blocks are observed to move out of rest. Consider analyzing the problem from the point at which the system is released from rest up to the point when m1 has displaced by an amount ℓ. Figure 7: Block 1 is held in place on a horizontal table (with friction) with an attached, massless rope running from it to an affixed pulley, and then threading through a movable pulley to then attach to the ceiling. The movable pulley is attached to a hanging Block 2 via a massless cable. The system is released and is seen to displace, with work considerations to be investigated up to the point when Block 1 displaces by an amount ℓ. (a) Determine the work done by each individual force acting on each individual block for the considered displacement. (b) Determine the speed of each block for the considered displacement.

A 2.30 kg thin, spherical shell of radius 0.160 m is released from rest at point A in the figure below, its center of gravity a distance of 1.80 m above the ground. The spherical shell rolls without slipping to the bottom of an incline and back up to point B where it is launched vertically into the air. The spherical shell then rises to its maximum height hmax at point C. HINT (a) At point B, find the spherical shell's translational speed vB (in m/s ). m/s (b) At point B, find the spherical shell's rotational speed ωB (in rad/s). rad/s (c) At point C, find the spherical shell's rotational speed ωC (in rad/s). rad/s (d) At point C, find the maximum height hmax of the spherical shell's center of gravity (in m ). m
