You release a 3-kg firecracker from rest. At t = 0.4 s, the firecracker is moving downward with speed 4 m/s. At this same instant, the firecracker begins to explode into two pieces with masses mtop = 1 kg and mbottom = 2 kg. At the end of the explosion (t = 0.8 s), the top piece is moving upward with speed 4 m/s. Determine the velocity of the bottom piece at t = 0.8 s. (Hints: Make a momentum vector diagram. Don’t forget to include impulse in your diagram!)
