A hollow rod has frictionless inner walls. Inside the rod are two small spheres that are kept on either side of the centre of rod. The rod is rotated about its central axis which is perpendicular to the plane of rotation. If the rod had been rotated by an impulsive torque which gave it an instantaneous angular velocity of 5rad/s, what will be the angular velocity after some finite but long time ‘t’? Assume no external forces act on rod after the impulse. Also state what will happen to the spheres in the centre of the rod. The rod has a mass =2kg & length =10cm. The two spheres have a mass =1kg each.
A sphere of diameter 42 cm is melted and bullets are formed from it. The bullet has circular cylindrical shape from one side and conical from other side. The radius of the base of the cylindrical part of the bullet is 6 cm and the cylindrical part has thrice as much length as the conical part. Find how many such bullets can be formed if the curved surface area of the cylindrical part of a bullet is 79.2 cm2.
