Hello:(adsbygoogle = window.adsbygoogle || []).push({});

I am wondering if anyone can help with the following problem:

A pellet of mass M is fired at an angle of 60 to the horizontal. In midair (when the vertical velocity is zero) the pellet explodes into 2 pieces. A piece of mass 1/2*M has a speed of 0 and falls immediately to the ground. The second piece of mass 1/2*M continues flying. How far does the second piece fly?

I am wondering if someone can explain the significance of the explosion? Wouldn't the vertical acceleration be the same (-g)? And I thought that there is no horizontal acceleration?

This is in the center of mass chapter, but I don't see how this has to do with center of mass?

Sorry for not understanding.
