A bomb with 8 x 10 with the power of 4 J of potential energy explodes. Assume 20 percent of its potential energy is converted to the kinetic energy of the metal pieces flying outward (shrapnel). The total kinetic energy is 1.6 x 10 to the power of 4 J. Assume the average mass of the shrapnel is 0.4 kg and that there are 200 pieces. What is the average speed of one piece?
