1. The problem statement, all variables and given/known data A horizontal cylinder on frictionless bearings has a moment of inertia of 0.8kg*m^2 and a radius of 22cm. A 15 kg mass is attached to a 8kg mass with a massless string wrapped around the cylinder. The string does not slip on the cylinder. If the 15 kg mass is released from rest 3.4m above the floor, a) what is the velocity of the 8kg mass when the 15kg mass hits the floor? b) what is the angular velocity of the cylinder when the 15kg mass hits the floor? 2. Relevant equations Mg-T=Ma T-mg=ma V^2=V0^2 + 2a(y-y0) mgh=1/2mv^2 + 1/2Iω^2 3. The attempt at a solution a)I solved for T in one of the above equations and plugged into the other equation. Then I plugged in the masses and solved for the acceleration which should be the same for both boxes and I got 2.9826 m/s^2 for a. I then used the third equation given that the original velocity is zero, the height is 3.4m, and the acceleration calculated earlier to be 2.9826, and calculated the final velocity which I got as 4.50m/s. b) I used conservation of energy and used the fourth equation. I plugged rω in for v and then plugged in for the variables known and solved for ω which I got to be 25.6 rad/s.
