Question
Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 65 N and that the pressured water provides a frictionless support. How long will it take her to rotate the sphere one time, starting from rest?
Express your answer with the appropriate units.
The photograph below shows a girl pushing on a large
stone sphere. The sphere has a mass of 8200 kg and
a radius of 90 cm and floats with nearly zero friction on
a thin layer of pressurized water.
