Applying Newton's Three Laws
A 5kg picture frame is held up by two ropes, each inclined 45 o below vertical, as shown below. What is the tension in each of the ropes?
Consider a 10kg block resting on a frictionless plane inclined 30 o connected by a rope through a pulley to a 10kg block hanging free, as seen in the figure below. What is the direction and magnitude of the resulting acceleration of the 2-block system?
Two 10kg blocks are connected by a rope and pulley system, as in the last problem. However, there is now friction between the block and the incline, given by μ s = .5 and μ k = .25 . Describe the resulting acceleration.
