Question

A 6. 0kg box is on a frictionless 45 degree slope and is connected via a massless string over a massless, frictionless pulley to a hanging 2. 4kg weight. What is the tension in the string if the 6. 0kg box is held in place, so that it cannot move? Express your answer to two significant figures and include the appropriate units. If the box is then released, which way will it move on the slope? What is the tension in the string once the box begins to move? Express your answer to two significant figures and include the appropriate units.

Explanation / Answer

if the box is held T=2.4*g =23.52N if moving mg*sin45-T=6*a T-2.4g=2.4a T=25 N
