In Problem 4.28, determine the magnitude of the velocity of A and B when they have moved 500 mm if the coefficient of kinetic friction between all surfaces is

Strategy: The simplest approach is to apply the principle of work and energy to A and B individually. If you treat them as a single system, you must account for the work done by internal friction forces. Sec Example 4.3.

Problem 4.28

The masses of the three blocks areand me = 12 kg. Neglect the mass of the bar holding C in place. Friction is negligible, By applying the principle of work and energy to A and B individually, determine the magnitude of their velocity when they have moved 500 rom.
