Consider a 0.05 kg stick of dynamite that is launched vertically upward. At its apex, the dynamite explodes into two unequal chunks of 0.01 kg and 0.04 kg. You know a couple of things: that the larger chunk is moving vertically downward immediately after the explosion, that 5200 J of thermal energy is generated during the explosion, and that 9900 J of potential energy is lost during the explosion. What must be the magnitude of the smaller chunk’s velocity immediately after the explosion?
