b. The trains have a top speed in a straight line of 20ms-1. In order to ensure that passengers are comfortable, the acceleration and deceleration of the trains are limited to 3ms-2. i. The route is counterclockwise starting from stop A and remains stationary at each stop for 2 minutes. Assuming that the train's acceleration/deceleration is constant, calculate the time taken to reach each stop - including the time taken to go back to stop A.

Iwould sure like to answer your question but i honestly just don’t know

I'll do it rn and then answer

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.
