Locomotive

Locomotive pulled a train permanent load of 200 kN horizontally along the track of 5km. What work it done?

Correct result:

W =  1000 MJ

Solution:

W=200000 5000/1000000=1000 MJ



We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you!
