##### Reference no: EM13543681

A 5.3kg box is on a frictionless 36^\circ slope and is connected via a massless string over a massless, frictionless pulley to a hanging 1.6kg weight. A- What is the tension in the string if the 5.3kg box is held in place, so that it cannot move? B- If the box is then released, which way will it move on the slope? C- What is the tension in the string once the box begins to move?
