In a test of a new missile defense system, a missile is fired on a trajectory that would directly
strike the center of a certain bunker, which is 20 m long. 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 52.7 m apart, by how much does
the larger fragment miss hitting the bunker? Ignore the effects of air resistance. (Hint: Think
about the trajectory of the missile if it had not exploded into two fragments. Is the explosion
an internal interaction or an external interaction? How does each kind of interaction affect
the motion of the center of mass of a system?)
