Find its power consumption rate in kilowatts

Reference no: EM13702798

Solve the following questions:

Question I: A light-rail commuter train draws 545 A of 660-V DC electricity when accelerating. What is its power consumption rate in kilowatts?

(in kW)

Question II: How long does it take to reach 25.0 m/s starting from rest if it's loaded mass is 5.50×104 kg, assuming 90.0% efficiency and constant power? (in s) Find its average acceleration.

(in m/s^2)

Question III: What is the ratio of the acceleration you found for the light-rail train compares to what might be typical for an automobile? (A typical automobile can accelerate from 0 to 60 mph in 10 s.)

I don't just need an answer, work and explanations/walkthrough would be much appreciated! Thanks
