A particle P is to be projected from a fixed point A on the ground with a fixed speed u . Another particle Q is also to be projected from a point B which is directly above the point A . The trajectory of the particle Q touches all possible trajectories (for different angle of projection) of the particle P in the vertical x-y plane. Find the equation of trajectory of the particle Q . (Take the point A as origin, horizontal axis x- axis and vertical axis y- axis Consider the figure.)
