a projectile that is fired from a gun has an initial velocity of 90km/h at an angle of 60 degrees above the horizontal. when the projectile is at the top of its trajectory an internal explosion causes it to separate into two fragments of equal mass. one of the fragments falls straight downward as though it had been released from rest. how far from the gun does the other fragment land. I don't even know where to start. Thanks
