## Homework Statement

In the figure shown.Find :

a)acceleration of 1 kg,2kg,and 3kg blocks and

b)tensions T1 and T2

## The Attempt at a Solution

2T1=2T2=>T1=T2

T2=1*a ,where a is acceleration of mass 1kg

T2=a

Let a

_{r}be the acceleration of mass 2 kg and 3kg wrt to the 3rd pulley.then,

3g-T1=3a

_{r}

and T1-2g=2a

_{r}

solving a

_{r}=g/5

net acceleartion of 2 kg and 3kg is a-a

_{r}and a+a

_{r}

then what to do?
