1. Determine the horizontal velocity u with which a stone must be projected from point p of height h so that it may hit the inclined plane perpendicularly. Inclination is theta and inclined plane is kept just below point p at ground. Give the value in terms of g, h and cot theta.                                                                                                                                                                                                                                                                                             2. Point A moves uniformly with velocity v so that vector v is continually aimed at point B which in its turn moves rectilinearly with velocity u<v. Initially, u perpendicular to v and separation was l. How soon will the points converge.     Plz answer both the questions as I have exam tommorow.
