As shown, there is rotating spotlight at a perpendicular distance `h` from a horizontal floor. The light revolves at `N rev//min` about a horizontal axis perpendicular to the paper. Find the velocity of light spot traveling along the floor.

A rod of mass M and length L lying horizontally is free to rotate about a vertical axis through its end. A horizontal force F on the rod at the other end, the force always remains perpendicular to the rod. Find the angular velocity of the rod when it has turned an angle pi//2 .

A plate of mass m , length b, and breadth a is initially lying on a horizontal floor with length parallel to the floor and breath perpendicular to the floor. Find the work done to erect it on its breadth.

Two particles connected by a rigid light rod AB, lying on a smooth horizontal table. An impulse J is applied at A in the plane of thetable and perpendicular at AB. Then the velocity of particle at A is

A thin bar of mass M and length L is free to rotate about a fixed horizontal axis through a point at its end. The bar is brought to a horizontal position and then released. The axis is perpendicular to the rod. The angular velocity when it reaches the lowest point is
