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