Question Description

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?

Final Answer

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

mass of the engine=5kg

mass of each toy=1

total mass of toys=5 kg

total mass=10kg

force of locomotive=20N

weight of engine and masses=mass x acceration due to gravity

10 x 9.81

=98.1N

tension=98.1-20

78.1N

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