A 8000kg engine pulls a train of 5 wagons each of 2000kg along a horizontal track.if the ingine exerts a force of 40000 N and the track offers a friction force of 5000 N then calculate

(I)net accelerating force is
40000N-5000N
=35000N
(ii) acceleration=force/mass
35000/2000*5 (as there are 5 wagons)
=35000/10000
3.5 m/sec square
(iii) force of wagon 1 on wagon 2 = mass of 4 wagons *acceleration of train
2000*4*3.5
28000N.
Hope my ans. Helped you
