A body is thrown at an angle theta 0 with the horizontal such that it attains a speed equal to sqrt 2/3 times the speed of projection when the body is at half of its maximum height. Find the angle theta 0.

A truck starts from origin accelerating with a m s^-2 in positive x - axis direction. After 2 s as shown in figure. A particle is projected from point P with velocity u=10 sqrt(3) m//s along a direction perpendicular to plane OA. If the particle strikes plane OB perpendicular at Q. Calculate. two inclined planes OA and OB having inclinations 30^@ and 60^@ with the horizontal respectively intersect each other at O
