2) A shell with mass 4m is moving with a horizontal speed of 40 m/s at a height of 100 m. At this instant it explodes and splits into two pieces of equal masses. One of the pieces has zero speed after the explosion and lands directly below the point of explosion. Take the explosion time as t-0. (ignore the air resistance) a)-Where does the other piece land? b)- What is the velocity vector of the center of mass of the two fragment system 2 s after the explosion? c- What is the position vector of the center of mass of the two fragment system 2 s after the explosion?
