The power of a bus engine is transmitted using the belt-and-pulley arrangement shown. The engine turns pulley $A$ at ${?}_A=40\mathrm{rad}/\mathrm{s}$ clockwise. The hub at $D$ is rigidly connected to $B$ and turns with it. (Figure 1 ) Figure 1 of 1 Part $A$ Determine the angular velocity of the generator pulley $B$, measured clockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is clockwise and negative value if the angular velocity is counterclockwise. ${?}_B=?3\mathrm{d}/\mathrm{s}$ Part B Determine the angular velocity of the air-conditioning pulley $C$, measured clockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is clockwise and negative value if the angular velocity is counterclockwise.
