The electric motor of a model train accelerates the train from rest to 0.620m/s in 21.0ms.? The total mass of the train is 875g. a) Find the minimum power delivered tothe train by electrical transmission from the metal rails during the acceleration. b) Why is it the minimum power?I know how to do the average power, but this asking for minimum power, which sounds like instantaneous power to me. I know how to calculate the acceleration, which Iam assuming is...
