4PRACTICE PROBLEM
A physics student built a rotating device using a 1.1 m bar of negligible mass and a 75-gram sphere fixed to one end of the bar. The opposite end is supported by a fixed frictionless horizontal axis, making it possible to freely rotate the bar in a vertical plane. Find the minimum speed that the student should give to the sphere at its lowest position so that the sphere makes a full rotation.
