Question

The pulley in the figure (Figure 1) has radius 0.160 m and a moment of inertia 0.560 kg?m 2 . The rope does not slip on the pulley rim. Use energy methods to calculate the speed of the 4.00-kg block just before it strikes the floor. The pulley in the figure (Figure 1) has radius 0.160 m and a moment of inertia 0.560 kg?m 2 .

Explanation / Answer

The pulley in the figure has radius 0.160 m and a moment of inertia 0.560 kg*m^2 . The rope does not slip on the pulley rim.

The rope is exerting a force on the outer edge of the pulley. The force is the difference of the weights of the blocks.
Net force on the pulley = 4 * 9.8
