A cannonball is fired from ground level at an angle of 60.0 ° from horizontal at a speed of 72.5 m/s. What is the vertical component of the velocity at the time of launch?

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.

So are u adding some additional catalyst

120v is the answer i am positive tell me if this was correct
