Please only type answer For "The Atwood Machine", given the masses of the blocks (m1=2kg and m2=5kg), the mass of the pulley (M=1kg), and the radius of the pulley (R=20 cm) I would like you derive expressions for the acceleration of the system if we include the rotational motion of the pulley. Also derive expressions for the tensions involved. Explain how the acceleration would change if the system were mounted to the top of an elevator that is accelerating up at 5 m/s^2.
