In a test of a new missile defense system, a missile is fired on a trajectory that would directly strike a certain bunker. a laser flash from the bunker ignites the missile's fuel, causing it to explode into two fragments, one with 1.8 times the mass of the other. if the fragments land at the same time 45 m apart, by how much does the larger fragment miss hitting the bunker? ignore the effects of air resistance. (hint: the external gravitational interaction between the missile and the earth would have caused the missile's center of mass to reach the ground at the location of the bunker if the missile had not exploded.)
