A child's toy train involves an engine of mass 5.00 kg and 5 toy freight cars mass of 1.0 kg each. For simplicity treat the wheels of the freight cars as frictionless so that all traction is provided by the locomotive which can generate a force of 20 N. What is the tension in the coupling between the locomotive and the first car?

Thank you for the opportunity to help you with your question!

Mass of the engine=5kg

5 toys= 5kg

T=W+ma

 =100+10*0

100

Please let me know if you need any clarification. I'm always happy to answer your questions.

Can you explain how you got the equation?

Jun 8th, 2015

The equation of tension is normally =T=W+ma

Suppose the track has a 10 degree downgrade. What acceleration will the train have going uphill? (Assume the locomotive continues to generate the same force in its forward direction)
