Suppose a 69 kg person stands at the edge of a 7.8 m diameter merry-go-round turntable that is mounted on frictionless bearings and has a moment of inertia of 1600 kg*m^2. The turntable is at rest initially, but when the person begins running at a speed of 3.7 m/s (with respect to the turntable) around its edge, the turntable begins to rotate in the opposite direction. Calculate the angular velocity of the turntable.

momentum conservation
I1*W1= I2*w2
Wturntable=(massman*r^2)3.7(2PI/r)/1600
I1*W1= I2*w2
Wturntable=(massman*r^2)3.7(2PI/r)/1600
