The figure shows objects A and B thrown from point O with the same initial velocity v_0 and then traveling in parabolic motion past points P and Q, respectively. A was thrown upward by with respect to the horizon, while B was thrown in a horizontal direction. O and P are separated by a distance L from the horizon, and Q is a distance d from P in a straight line. How many times is d equal to L (but =15')?
