A small blob of putty of mass m falls from the ceiling and lands onthe outer rim of a turntable of radius R and moment of inertiaI0 that is rotating freely with angular speedω0 about its vertical fixed-symmetry axis.
(a) What is the post collision angular speed of theturntable-putty system?
(b) After several turns, theblob flies off the edge of the turntable. What is the angular speed of the turntable after the blob's departure?

A 65.0 kg base runner begins his slide into second base when he is moving at a speed of 4.5 m/s. The coefficient of friction between his clothes and Earth is 0.70. He slides so that his speed is zero just as he reaches the base.
assume a charge starts at rest on an equipotential surface, is moved off that surface, and then is eventually returned to the same surface at rest after a round trip. How much work did it take to do this? Explain.
