![SOLVED: A 3.00-kg object B is connected with a string to a 5.00-kg object A, which is connected with a second string over a massless, frictionless pulley to a 9.00-kg object C. SOLVED: A 3.00-kg object B is connected with a string to a 5.00-kg object A, which is connected with a second string over a massless, frictionless pulley to a 9.00-kg object C.](https://cdn.numerade.com/ask_previews/ae4a1c6c-2925-47e3-9e1b-cdcd26eab393_large.jpg)
