Homework Statement
A mass m1 is hung on a pulley with another pulley on th eother side with two masses;m2 and m3.Find the accelerations of the masses
Homework Equations
F=M.a
a1=-(a2+a3)/2
The Attempt at a Solution
So in my book ,the solution provided was 2T-m1g=m1a1
T-m2g=m2a2 and T-m3g =m3a3.My question is why did the two equations for mass 2 and mass 3 seems to have both objects to move upwards,shouldn't one move down and one up ?why is the equation of motion like that ?
