The figure below shows a system consisting of a block of mass 5 kg and a wedge that are moving to the right with a common acceleration of 2 m/s². A massless string connects the block to the support at A. Find the tension in the string. Ignore friction between all surfaces in contact. 5 kg a = 2 m/s² 30
The figure below shows a block of mass 2 kg sitting on top of another block of mass 5 kg which rests on a frictionless horizontal surface. The coefficient of static friction between the two blocks is us. A horizontal force F of magnitude 21 N is applied to the 5 kg block. Find the minimum value of μs such that the two blocks accelerate together without slipping. (Hint: first find the common acceleration of the two blocks.) 2 kg 5 kg F
