Suppose a car that has a mass of 1198.5 kg is about to crash into a wall traveling at 27.0 m/s. What is the impulse between the wall and the car?
Note this is not a realistic example like in the video.
The units will be in N*s.

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.

Answer (d) the universe had cooled enough for atoms to combine, protons and neutrons were too far apart to form nuclei;
