Hint: Call the mass of the cart m. The mass will cancel! How many forces act on the cart at the top of the loop? What is the cart's acceleration at the top of the loop? m/s² What is the cart's speed at the top of the loop? m/s From what height must the cart be released? m A ot h 18m reference level
