A potter’s wheel with a moment of inertia of 2.5 x 10-2 kg m2 is spinning at 33.3 rpm. A 0.25 kg lump of clay is dropped vertically onto the potter’s wheel, 0.20 m from the center of rotation. Find the angular speed of the system after the clay is added.

Alead ball is dropped into a lake from a diving board 5m above the water . it hits the water with a certain velocity and then sink with constant velocity in bottom . it reaches the bottom 5 second after it is dropped if g= 10m/s2 . find depth of the lake and average velocity of the ball ?
