QUESTION:

Integrated Concepts 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 4? does it take to reach 20.0 m/s starting from rest if it's loaded mass is 5.30×10? kg , assuming 95.0% efficiency and constant power? (c) Find its average acceleration. (d) Discuss how the acceleration you found for the light-rail train compares to what might be typical for an automobile. Given: Current: 630 A Voltage = 650-V DC Mass = 5.30×10? kg , Distance-= 20.0 m/s Efficiency= 95.0% Calculate: 1) Power consumption rate in kilowatts=? 2) Time or duration to reach 20.0 m/s starting from rest if it's loaded mass is 5.30×10? kg , assuming 95.0% efficiency= ? 3) Find its average acceleration. 4) Comparing the calculated acceleration with typical automobile acceleration.
