Incline Plane Drawing

A cart connected to a hanging mass is free to move on an incline plane with an angle of θ degrees.

Using the appropriate data in the table above, determine which way the hanging mass will move (up or down) and the tension in the string connecting the cart and hanging mass).

All work must be shown on the back of this page. Your work should include free body diagrams.

Which way will the hanging mass move? Up Down

What is the tension of the string while the cart and hanging mass are moving?

If you prevent the cart from moving by holding the cart with your hand, what would the tension of the string be? Explain your answer.
