13. Problem based on Second law of motion

An 6000 \(kg\) engine pulls a train of 7 \(wagons\), each of 2000 \(kg\), along a horizontal track. If the engine exerts a force of 40000 \(N\) and the track offers a friction force of 6500 \(N\), then calculate:

 

(a) the net accelerating force and

 

(b) the acceleration of the train

 

(Enter the values up to two decimal)

  

Answers:

 

(a) Net accelerating force \(=\)  \(N\)

 

(b) Acceleration of the train \(=\)  $m{s}^{-2}$
