A block of mass 0.74 kg is suspended by a string which is wrapped so that it is at a radius of 0.069 m from the center of a pulley. The moment of inertia of the pulley is 4.90×10-3 kg·m2. There is friction as the pulley turns. The block starts from rest, and its speed after it has traveled downwards a distance of D= 0.77 m, is 2.133 m/s. Calculate the amount of energy dissipated up to that point.

A uniform rod is set up so that it can rotate about an axis at perpendicular to one of its ends. The length and mass of the rod are 0.873 m and 1.11 kg, respectively. A force of constant magnitude ?F acts on the rod at the end opposite the rotation axis. The direction of the force is perpendicular to both the rod's length and the rotation axis. Calculate the value of ?F that will accelerate the rod from rest to an angular speed of 6.35 rad/s in 8.37 s.
