## Homework Statement

the question exactly states that

a 8000 kg pulls a train of 5 wagons each of 2000 kg along a horizontal path

now if the train exerts a force of 40000 N , and the track offers a friction of then calculate

a_NET FORCE

b_ACCELERATION OF TRAIN

c_FORCE OF WAGON 1 ON WAGON 2

**2. The attempt at a solution**

a_i can easily calculate the net force by subtracting the frictional force from the total force provided by engine

b_now here arises my confusion

the question considered that the engine is the first wagon but i didnt

so when i filtered my answers on that

the trains acceleration was thought as the acceleration of all the wagons except ... but that doesn't make sense to me... please help?

c_now this question is doing something perfectly alien to me , it is taking the acceleration of all the wagons multiplied with the mass of the engine wagon...please help?

**3.here is a link to the question and another for verification**
