Question

Suppose a fireworks shell explodes, splitting into three large pieces for which air resistance is negligible. How does the explosion affect the motion of the center of mass? (Assume only gravity is acting before and after the explosion).

The center of mass stops moving.

The center of mass continues on the same trajectory.

The center of mass follows the heaviest fragment.

More information is needed.

Explanation / Answer

Answer :The center of mass continues to move on same trajectory.

Explanation:

As the only external force acting on the system was gravity, before, during and after explosion, so acceleration of centre of mass will remain same throught the motion, so it wont change its trajectory.
