The Atwood Machine consists of two masses suspended form a fixed pulley. If the first mass is 0.55kg and 0.8kg,
(a) what is the acceleration of the system?
(b) What is the magnitude of the tension in the string? (consider the pulley to be frictionless and the masses of the string and the pulley to be negligible.)
