Q1/ A train consists of locomotive and (100) hopper cars. The mass of locomotive is 181.437M9 and the mass of each car is 90.72 Mg. If the locomotive exerts a friction force of 178 kN on the rails in starting the train from rest, compute the forces in couplers 1 and 100. Assume no slack in the couplers and neglect friction associated with the hopper cars. Also find the velocity of the train after 30 secont from rest
