Question:

A light-rail commuter train draws 630 A of 650-V DC electricity when accelerating.

(a) What is its power consumption rate in kilowatts?

(b) How long does it take to reach 20.0 m/s starting from rest if its loaded mass is 5.30 × 104 kg, assuming 95.0% efficiency and constant power?

(d) Discuss how the acceleration you found for the light-rail train compares to what might be typical for an automobile.
