A 2.3kg , 20-cm-diameter turntable rotates at 100 rpm on frictionless bearings. Two 500g blocks fall from above, hit the turntable simultaneously at opposite ends of a diagonal, and stick. What is the turntable's angular velocity, in rpm, just after this event? I first cacluted the angular momentum as .120428 using I*W so I then set that equal to I*W where I=.5(3.3)(.1)^2 and w is 2pi(frequency) and tried solving for frequency. and converting that back to rpm. But 69.7 rpm wasn't correct so I'm missing something or approaching this wrong! Any suggestions?
