A hanging mass, M1 = 0.18 kg, is attached by a light string that runs over a frictionless pulley to the front of a mass M2 = 0.47 kg that is initially at rest on a frictionless table. A third mass M3 = 0.71 kg, which is also initially at rest on a frictionless table, is attached to the back of M2 by a light string.
A) Find the magnitude of the acceleration, a, of mass M3.B) Find the tension in the string between masses M1 and M2.
