A 5.8kg box is on a frictionless 40%u2218 slope and is connected via a massless string over a massless, frictionless pulley to a hanging 1.7kg weight.
Part A What is the tension in the string if the 5.8kg box is held in place, so that it cannot move?
Part B If the box is then released, which way will it move on the slope?
Part C What is the tension in the string once the box begins to move?
