Questions based on Relative velocity and Multiplication of Vectors

If rod is thrown upward with initial angular velocity and velocity of centre of mass then its momentum changes but angular velocity remains same. Torque on rod about cente of mass due to gravitational force is zero.

A rod of mass m and length l is kept on a surface that has no friction. If a ball comes & hits the lower end with a velocity v, then the velocity of centre of mass will be

A wheel rolls purely on ground. Find a point on the periphery of a body which has a velocity equal to the velocity of the centre of mass of the body.

If the rod were translating as well as rotating, what will be its emf? Assume that the centre of mass has a velocity v and the rod is rotating with an angular velocity omega atout its centre of mass.

A hemisphere of radius R and mass 4 m is free to slide with its base on a smooth horizontal table . A particle of mass m is placed on the top of the hemisphere . The angular velocity of the particle relative to centre of hemisphere at an angular displacement theta when velocity of hemisphere has become v is
