Question

Question 11. A railway train weighing 1000 quintals is moving on a level line from rest. It attains a speed of 54 Km/ Hr in 5 mins. Find the mean pull exerted by the engine if the resistance to its motion is 5Kg/ Quintal. (Marks 5)​

Answer 1

Answer:

Explanation:

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 KW

Vol 96

So power of engine is 500 KW
