I need some help. First question: Is the tension of the string is the same or different?

A pulley of moment of inertia 2.7 kg [FONT="]· m

^{2}is mounted on a wall as shown in the following figure. Light strings are wrapped around two circumferences of the pulley and weights are attached. Assume the following data:

*r*

_{1}= 47 cm,

*r*

_{2}= 20 cm,

*m*

_{1}= 1.0 kg,

and

*m*

_{2}= 1.9 kg.

What is the angular acceleration in rad/$s^2$ of the pulley?

(b)

What is the linear acceleration (in m/s

^{2}) of the weights?
