A potter's wheel with rotational inertia 6.92kg⋅m2 is rotating freely at 19.3 rpm. The potter drops a lump of clay onto the wheel, where it sticks 48.0 cm from the rotation axis. With the clay on the wheel, the wheel's rotation rate is 17.4 rpm. What is the mass of the clay?
The initial angular momentum of potter’s wheel is,Li = IiѠiHere, Ii is initial moment of inertia of wheel, Ѡi is initial angular velocity.Therefore,Li = (6.92 kg .m2) (19.3 rpm)After...
