Hi all
1 ) A train of 3000 KN weight starts from rest and reached a velocity of 54 km/h after one min . if the frictional resistance of the track is 5N/KN of the train's weight . Find the tractive force developed by the engine ?
I don't understand what is mean "tractive force " ??
anyway I start solve the question
w = 3000 kN
mass = 305810
u = 0
v = 54 km/h
v = u + at
a = 0.25
F = m X a
F = 305810 X 0.25
