Question: The device shown below is Atwood's machine. Assuming that the masses of the string and the frictionless pulley are negligible. The masses of the two

The device shown below is Atwood's machine. Assuming that the masses of the string and the frictionless pulley are negligible. The masses of the two blocks are m1= 4.00 kg and m2= 6.00 kg.

A: What is the magnitude of the tension in the string ?

B: If the blocks are released from rest, what are the speeds of the two blocks after 3 seconds ?

C: If the pulley is NOT massless, how would the acceleration of the blocks change? (increases or decreases) Please explain your answer.
