Question: A projectile is fired from point A at an angle above the horizontal. At its highest point, after having traveled a horizontal distance D from

A projectile is fired from point A at an angle above the horizontal. At its highest point, after having traveled a horizontal distance D from its launch point, it suddenly explodes into two identical fragments that travel horizontally with eqna1 but opposite velocities as measured relative to the projectile just before it exploded. If one fragment lands back at point A, how far from A (in terms of D) does the other fragment land?
