A woman whose mass is 50.7 kg stands at the rim of a horizontal turntable
which has a moment of inertia of 387 kg m2 about the axis of rotation and a radius of 2.88 m. The system is initially at rest and the turntable is free to rotate about a frictionless, vertical axle through its center. The woman then starts walking around the rim in a clockwise direction (viewed from above) at a constant speed of 1.16 m/s relative to the ground.
What will the motion of the turntable be, relative to the ground?
Answer options are…
