Question

An 8000kg engine pulls a train of 5 wagons,each wagon of mass 2000kg,along a horizontal track.If the engine exerts a force of 40000N and the track offers a friction force of 5000N
calculate
i)the net accelerating force,
ii)the acceleration of the train,and
iii)the force of wagon 1 on wagon 2

please solve it step by step and give me the answer fast ​

Explanation:

Mass of engine=8000kg

No. of wagons = 5

Mass of each wagon= 2000kg

Total mass of wagon = (5*2000)kg=10000kg

Total mass of train = [ Total mass of engine+ Total mass of wagons] = (10000+8000)kg= 18000kg

Now,

Force exerted by engine =40000N

Friction force of track = 5000N

a) net accelerating force=(40000-5000)N

$\large\blue{\boxed{=35000N}}$ ( Ans)

b) the acceleration of the train :-

==>F=ma

==>35000N=18000kg* a

==>a= 35000N/18000kg= 1.944ms-²( Ans )

c) ==>F=ma

==>F=(8000*1.944)=15552N (Ans)
