[QUOTE="AndreewL, post: 5470380, member: 593681"] [h2]Homework Statement [/h2] [LIST=1] [*]A large wooden turntable in the shape of a flat disk has a radius of 1.50 m and a total mass of 100 kg. The turntable is initially rotating about its vertical axis through its centre with an angular velocity of 2.50 rad/s. From a very small height a 100 kg sand bag is dropped vertically onto the turntable at a point near the outer edge. a) Find the angular velocity of the turntable after the sand bag is dropped (assume that the bag can be treated as a point ). b) Calculate the kinetic energy of the system before and after the bag is dropped. Why are the kinetic energies not equal? [/LIST] [B] [/B] [h2]Homework Equations[/h2] I=1/2MR^2 [h2]The Attempt at a Solution[/h2] I've been stuck on this for a couple days now just playing around with it and haven't seem to get anywhere towards the answer.
