1. The problem statement, all variables and given/known
Consider two objects with M1 greater M2 connected by a light string that passes over a pulley having a moment of inertia I about its axis of rotation. The string does not slip on the pulley or stretch. The pulley turns with friction. The two objects are released from rest separated by a vertical distance 2h
(a) use the principal of conservation energy to find the translational speeds of the objects as they pass each other
(B) find angular speed of the pulley at this time
m1gh = m2gh + 1/2mv^2 + 1/2m1v^2 + 1/2I(V^2/R^2)[/B]
V= sqrt(2(m1gh-m2gh)/m2 + m1 + I/R^2)
Is this the right answer because it considers when the m1 block moves 2h down not when it passes the other block. How is this solved then??
