The pulley in (Figure 1) has radius 0.160 mm and a moment of inertia 0.380 kg⋅m2kg⋅m2. The rope does not slip on the pulley rim.

The pulley in the figure 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.

9.76 - The pulley in Fig. P9.76 has radius 0.160 m and moment of inertia 0.380 kg.m. 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. Figure P9.76 4.00 kg 5.00 m 200 kg

A pulley with a radius of 3.0 cm and a rotational inertiaof4.5×10−3 kg ·m2 is suspended from
the ceiling. A rope passes over it with a 2.0-kg block attachedtoone end and a 4.0-kg block
attached to the other. The rope does not slip on the pulley.Whenthe speed of the heavier
block is 2.0m/s the kinetic energy of the pulley is:
A. 0.15 J
B. 0.30 J
C. 1.0J
D. 10 J
E. 20 J
