Question

(Figure 1) illustrates an Atwood's machine. Let the masses of blocks A and B be 7.50 kg and 1.50 kg , respectively, the moment of inertia of the wheel about its axis be 0.220 kg⋅m2, and the radius of the wheel be 0.120 m. There is no slipping between the cord and the surface of the wheel.

Part A

Express your answer with the appropriate units.

Part B

Find the magnitude of linear acceleration of block B.

Express your answer with the appropriate units.

Part C

Find the magnitude of angular acceleration of the wheel C.

Express your answer in radians per second squared.

Part D

Find the tension in left side of the cord.

Express your answer with the appropriate units.

Part E

Find the tension in right side of the cord.

Express your answer with the appropriate units.
