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 mcdot s^(-2) ? ( 1 tonne = 10^(3) kg )

1.	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 mcdot s^(-2) ? ( 1 tonne = 10^(3) kg )
Answer» ANSWER :392 N; (II) 10388 N
