Please, upload your detailed solution (every step) thank you so much! A woman is standing at the rim of a nonuniform cylindrical horizontal platform initially at rest. The platform is free to rotate about frictionless orthogonal axle that goes through its center and has 4 m in diameter and moment of inertia of 500 kgm2. The woman then starts walking along the rim in clockwise direction at a constant speed of 1.50 m/s relative to the Earth. If a woman has 60 kg, how much work does she do to set herself and the platform into motion?
Select one:
a. -0.36 J
b. 0.36 J
c. 99.9 J
d. 67.5 J
e. 32.4 J
