rotational motion and moment of inertia---HELP!
Two masses m1=2.00 kg and m2=1.00 kg are linked by a thread and thrown over a pulley whose mass is 1.00 kg. The radius of the pulley is 0.200 m.
a) Find the acceleration a with which the weights move
b) the tensions T1 and T2 of the threads which the masses are attached to.
Consider the pulley as a homogeneous disk. Disregard friction.
Well, i tried to use the energy method because i know how to do that. But I'm having a problem because the problem doesn't state any given energy. please help me
