How much force would be exerted to move a locomotive with one car attached?
The total weight of the locomotive and car is 200,000 lbs, and the coefficent of friction is .02" of the wheels on the rail. Assumed to be the coefficient is for static friction. Both the car and locomotive have 4 wheels in contact with the rail (8 total wheels).

The force required will be the total force to overcome static friction. Let's assume the weight is evenly distributed across the 8 wheels, so the normal force (the weight) times the static coefficient of friction is required to nudge the locomotive:
200,000 *.02

Force = mass x acceleration. So you would need atleast 200,000 pounds of force to move the locomotive. I am rusty in my physics.
