Question

a train weighing 1000ton is moving on a horizontal track with a uniform velocity of 10m/s. the total resistance to the motion of the train is 5kgf per ton. if g= 10m/s2, then what is the power of the engine?

Answer 1

Step-by-step explanation:

Given A train weighing 1000 ton is moving on a horizontal track with a uniform velocity of 10 m/s. the total resistance to the motion of the train is 5 kgf per ton. if g= 10 m/s2, then what is the power of the engine?

We know that Resistive force F = m g

                                                    = 5 x 1000 x 10

                                                   = 50 K N

We know that Power P = force x velocity

                                     = 50 K N x 10

                              P = 500 K W

So power of engine is 500 KW
