Question

A small blob of putty of mass m falls from the ceiling and lands on the outer rim of a turntable of radius R and moment of inertia I0 that is rotating freely with angular speed omega 0 about its vertical fixed-symmetry axis. (Use any variable or symbol stated above as necessary.) What is the postcollision angular speed of the turntable-putty system? omega f = After several turns, the blob flies off the edge of the turntable. What is the angular speed of the turntable after the blob's departure? omega =

Explanation / Answer

I*w = (I+mR^2)*w1 where I is moment of inertia of turn table m is mass of blob R is radius of turn table w is initial angular speed of table w1 is the angular velvity of table and blob both then, w1 = Iw/(I + mR^2) in b part the angular velcity of turn table vl be equal to its initial angular velocity i.e., w
