Mass m2 rests on an incline and attaches to a string that goes over a pulley, where mass m1 hangs on the other side of the incline.

Question

Assume that there is no friction between m2 and the incline, that m2 = 5.1 kg, m1 = 0.9 kg, the radius of the pulley is 0.10 m, the moment of inertia of the pulley is 3.3 kg m2, and θ = 26.0°.

I've found the mechanical energy to be equal to 0, and the new gravitational potential energy of m2 once it moves 0.9 m down the incline to be about -20. However, I'm still having trouble solving what the speed of the masses at that position (.9 down the incline), and what the kinetic energy of the pulley would be at that instant. Any help is very appreciated!!
