**PLEASE HELP ME!!!! Pulley-Mass Problem**

**Ok guys, here's the problem. A 1.53kg mass hangs on a rope (negligible mass) wrapped around a frictionless pulley of mass 7.07kg. The radius of the pulley is .66 meters. What is the acceleration of the mass?**

update!

in response to berkeman's post, yes,the mass will freefall. i just need to know at what rate the mass will accelerate when it falls. sorry for not clarifying.

**2. Homework Equations**

Torque might be a factor:

T= mgr

T=Inertia x alpha

Torque might be a factor:

T= mgr

T=Inertia x alpha

**From there, I really don't know what to do. PLEASE help me. I need the answer as soon as possible.**
