Suppose that the quarterback takes 0.30 s to return to the ground after throwing the ball. how far d will he move horizontally, assuming his speed is constant?

Horizontal velocity = 0.08 m/s
acceleration = 0 in the x axis
distance = speed * time
distance = 0.08 * 0.3
distance = 0.024 m

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.

Imma say go with a (:
