Question

A firework is shot into the air at an angle and explodes into a spherical bouquet of sparkles. Assuming no air resistance, what path does the center of mass for all the pieces of the exploded firework follow? (a) The center of mass follows a new parabolic path that has it land beyond where the original, pre-explosion parabola would have landed because of the force from the explosion. (b) The center of mass follows a new parabolic path that has it land nearer to its launch point than the original, pre-explosion parabola would have landed because of the forces from the explosion. (c) The movement of the center of mass cannot be determined without precise information about the forces from the explosion. (d) The center of mass falls straight downward under the influence of gravity. (e) The center of mass continues along the same parabolic trajectory it was on before it exploded because of the conservation of momentum.
