"The electric motor of a model train accelerates the train fromrest to 0.620 m/s in 21.0 ms. The total mass of the train is 875 g.Find the average power delivered to the train during itsacceleration."
I know the answer is 8.01 W, but can anyone elaborate why that is.Also, I don't know what the unit "W" means. Unfortunately, myteacher has not covered that yet. I don't believe it stands for"Work" in my opinion.
Thank you
