A bomb is dropped from a plane flying horizontally with uniform speed. Show that the bomb will explode vertically below the plane.Is the statement true if the plane flies with uniform speed but not horizontally?

A uniform rod of length L lies on a smooth horizontal table. A particle moving on the table strikes the rod perpendicularly at an end and stops. Find the distance travelled by the centre of the rod by the time it turns through a right angle. Show that if the mass of the rod is four times that of the particle, the collision is elastic
