A 3-kg hammer is on a 30-m high beam at a construction site. If the hammer is accidentally knocked off the beam, how fast (m/s) will it go just before it strikes the ground. Ignore air resistance. Use g= 10m/s^2. ROUND YOUR ANSWER TO 1 DECIMAL

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.
