Three masses are connected by a light string that passes over a frictionless pulley. On the right is tension one holding a 6.5 kg mass. On the left, the top mass of 4.05 kg is held by tension 2 and below that mass is tension 3 holding a 2.4kg mass.
(a) What is the magnitude of the acceleration of the system?
(b) What are the magnitudes of the three tensions in the string?
