A shell at rest explodes into two fragments, one with a mass of im1 = 2.0 kg and the other m2 = 5.0 kg. If the 2nd fragment gains K2 = 100 J of kinetic energy from the explosion, how much kinetic energy does the lighter one gain, and what is the magnitude of the impulse it experiences from the explosion?
