Um veículo parte do repouso em movimento retilíneo e acelera com aceleração escalar constante e igual a 2,0 m/s2. Pode-se dizer que sua velocidade escalar e a distância percorrida após 3,0 segundos, valem,
respectivamente:
A. 6,0 m/s e 9,0m;
B. 6,0m/s e 18m;
C. 3,0 m/s e 12m;
D. 12 m/s e 35m;
E. 2,0 m/s e 12 m.

50 meters per 5 seconds

The answer would be a

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.
