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?
