A uniform rod of mass m and length l is placed over a smooth horizontal surface along the y-axis and is at rest as shown in figure an impulsive force F is applied for a small time Δt along x-direction at point A. The x-coordinate of end A of the rod when the rod becomes parallel to x-axis for the first time is : [Initially, the coordinate of centre of mass of the rod is (0, 0)]

A thin uniform rod of mass m and length l is kept on a smooth horizontal surface such that it can move freely. At what distance from centre of rod should a particle of mass m strike on the rod such that the point P at a distance l3 from the end of the rod is instantaneously at rest just after the elastic collision?
