A 100-g firecracker is launched vertically into the air and explodes into two pieces at the peak of its trajectory. If a 72-g piece is projected horizontally to the left at 17 m/s what is the speed of the other piece? (absolute value) How much energy is released by the explosion, assuming it all goes to the fragments.
