Homework Statement
Given the system shown, if the pulley has frictionless bearings, find
a, the magnitude of the acceleration of the masses.
This is a modified Atwood's machine, instead of the 2nd mass hanging however, it is stationary on a table. The pulley is at the edge of the table and the 1st mass is hanging down. The mass on the table has a mass of 3kg, the hanging mass is 4kg. The pulley has an I of 1/2 kg*m^2 and a radius of .3m.
Homework Equations
F = Ma
T = Ia(angular)
T = r x F
The Attempt at a Solution
F = Ma
Mg - T2 = ma
also Torque = r x F
Torque = rTsin90
RT = Ia(angular)
rT = I (A/R) --> because linear accel = angular * radius
But from here I'm lost...
