A small block sliding down a frictionless hemispherical dome of radius \(R\).
A small block of mass \(0.20\text{ kg}\) is initially at rest at the apex of a smooth, frictionless hemispherical dome of radius \(R = 7.5\text{ m}\) fixed to a horizontal floor. The block is given a negligible push and begins to slide down the curved surface. What is the speed of the block at the instant it loses contact with the dome?
