In Fig. $10-61$ , four pulleys are connected by two belts. Pulley $A$ (radius 15 $\mathrm{cm} )$ is the drive pulley, and it rotates at 10 rad/s. Pulley $B$ (radius 10 $\mathrm{cm}$ ) is connected by belt 1 to pulley $A$ . Pulley $B^{\prime}$ (radius 5 $\mathrm{cm}$ ) is concentric with pulley $B$ and is rigidly attached to it. Pulley $C$ (radius 25 $\mathrm{cm} )$ is connected by belt 2 to pulley $B^{\prime}$ . Calculate (a) the linear speed of a point on belt $1,$ (b) the angular speed of pulley $B,(\mathrm{c})$ the angular speed of pulley $B^{\prime},$ (d) the linear speed of a point on belt $2,$ and $(\mathrm{e})$ the angular speed of pulley $C .$ Hint: If the belt between two pulleys does not slip, the linear speeds at the rims of two pulleys must be equal.)

A pulley with a mass of 1.35 kg and a radius of 0.3 m is shown in the diagram. You wind a massless string around the pulley and apply a force of 16 N. The pulley begins to rotate from rest. The tension in the string for 8 seconds is experienced by the pulley. The moment of inertia for the pulley is given by I = 1/2mR^2. What is the value of the angular acceleration of the pulley after 8 seconds? (a) a = 106.7 rad/s^2 (b) a = 23.7 rad/s^2 (c) a = 39.5 rad/s^2 (d) a = 79 rad/s^2
