An automobile having a mass of 1364kg strikes a wall with a speed of 4.57m/s. The car moves an additional 0.152m before coming to a stop. A. What force does the car exert on the wall at the moment of impact

B. How long did it take for the car to come to a stop?

C. Is the collision elastic? Explain in terms of energy.

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.
