Tension in connected carts
Two carts in a robot cart data logger have masses \(8\,\text{kg}\) and \(7\,\text{kg}\). A force of \(50\,\text{N}\) pulls the \(8\,\text{kg}\) cart. Ignore friction. Calculate the tension pulling the \(7\,\text{kg}\) cart. Use the diagram before entering the requested value. Enter the numerical result and choose the interpretation that matches the physics meaning.
Worked practice: physics data and result
Read the physical quantities first, then calculate the result and state what it means.
