A particle P is projected from a point O on a horizontal plane and moves freely under gravity. Its initial speed is ums and its angle of projection is sin() above the horizontal. At time 8s after projection, P is at the point 4. At time 32s after projection, P is at the point B. The direction of motion of Pat B is perpendicular to its direction of motion at 4. Find the value of u. Q5 * A. u=100 B. u=130 C. u=160 D. u=180
