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. |
Part A Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 55 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? |
Then solid sphere is moment of inertia (I) ,
I = 2/5 mr^2

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. Suppose that she pushes on the sphere tangent to its surface with a steady force of F = 75 N and that the pressured water provides a frictionless support. How long will it take her to rotate the sphere one time,...
