A bomb, originally sitting at rest, explodes and during the explosion breaks into four pieces of
exactly 0.25 kg each. One piece flies due south
at 10 m/s while another piece flies due north at
10 m/s. The other two pieces travel in
directions.

stands for electromotive force and it is measured in volts. despite its name, it is not actually the force in the sense of being a "pushing" or "pulling" (not measured in newtons).an equation that relates emf,  ℰ,  to a battery's terminal voltage, v, current, i, and internal resistance, r, is    ℰ = v + irin this case, the emf can be interpreted as a voltage—a difference in electric potential.i would not say that it would be considered an energy. if emf can be defined as the energy/work per a unit charge from a battery or other electric source, then it is not strictly energy.
