Question

a train of mass 500 metric tonnes moves with a velocity of 20m/son a level track.the force of friction acting on the train due to track is 10n per metric tonne.then power of engine to move train.?​

Answer 1

Answer:

f= m*g

f= 5*1000*10

f=50kn

p= force*velocity

p= 50kn*10

p=500kw

hope it helps you
