A 50 kg car collided with a tree on the road at a speed of 50 m/s and fell into a ditch 3 seconds after reversing at a speed of 10 m/s. If the depth of the hole is 10 times the ratio of the last minute velocity to the initial speed of the vehicle , then if a 0.1 kg ball is thrown down from this height at a speed of 10 m/s, a 0.5 kg mass rat for the momentary velocity before touching the ground .What speed will be gain tha rat

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.
