A catapult on a level field tosses a 3.0 kg stone a horizontal distance of 100 m.
A second 3.0 kg stone tossed in an
identical fashion breaks apart in the air into
two pieces, one with a mass of 1.0 kg and
one with a mass of 2.0 kg. Both of the
pieces hit the ground at the same time. If
the 1.0 kg piece lands a distance of 180 m
away from the catapult, how far away
from the catapult does the 2.0 kg piece
land? Ignore air resistance.

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.
