A block of mass 0.72 kilogram is suspended by a string which is wrapped therefore that it is at a radius of 0.057 meter from the center of a pulley. The moment of inertia of the pulley is 0.0040 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 meter, is 1.397 m/s. Compute the amount of energy dissipated up to that point.
