A railway engine pulls a bogie of mass 10 tonne (metric ton). Average resistance against motion due to friction etc. is 39.2 N per tonne. What will be the tension on the chain when (i) the train is moving with a uniform velocity (ii) the train is moving with an acceleration of 1 m`cdot s^(-2)` ? ( 1 tonne =` 10^(3)` kg )

Text Solution

Verified by Experts

The correct Answer is:
392 N; (ii) 10388 N
