Problem 12. A projectile is fired from a point A at an angle above the horizontal. At its highest point after traveling a horizontal distance D, it explodes into two

identical pieces that travel horizontally with equal but opposite velocities relative to the projectile just before it exploded.If one fragment lands back at point A, how far from A (in terms of D) is the second fragment?Hint: if you understand how to do this you do not really need to do any complicated calculations.
