Problem 84P

The pulley in ?Fig. P9.76? has radius 0.160 m and moment of inertia 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.

Step-by-Step Solution:

Solution 84P Step 1: Initially all the blocks and the pulley were not moving, so the total energy of the system was only the potential energy of the block of mass 4 kg at a height of 5 meters. The total energy was, E = mgh = 4 × 9.8 × 5 = 196 J . tot
