In the diagram shown, Block A is 34.5 kg and Block B is 11 kg. The incline on Block A's side makes an angle of 61.5∘ with the horizontal and the incline on Block B's side makes an angle of 29∘ with the horizontal. The coefficient of kinetic friction of Block A's incline is 0.16 and that of Block B's incline is 0.104 . Assume that Block A is initially (at t = 0) sliding up its incline at 5.2 m/s. Also assume the pulley is massless and frictionless. In your submitted work, be sure to show your neatly drawn free body diagrams for each mass (using a straight-edge). Identify each vector force (draw arrows) in the diagram and draw your axes for each diagram and show the component breakdown for each force. . . points will be lost for sloppy or incomplete drawings. You should have FOUR FBDs. . . one for each mass as Block A slides UP the incline (while Block B slides DOWN its incline), and one for each mass when Block A slides DOWN its incline (while Block B slides UP its incline).

An m = 3.32 kg block situated on a rough incline is connected to a spring of negligible mass having a spring constant of k = 125 N/m, as seen in the figure below. The pulley is frictionless and massless. The block starts at rest at the position where the spring is unstretched (at equilibrium). The block moves 19.1 cm down the incline before coming momentarily to rest (this is the magnitude of the distance the block moves, not its vertical displacement). Take θ = 31.5∘. 12 Calculate the coefficient of kinetic friction between block and incline.

The crates A and B of mass mA = 50 kg and mB = 90 kg, respectively, are connected by a pulley system. The system is released from rest on the inclined surfaces for which θ = 30∘. Friction between A and the inclined surface on which it slides is insufficient to prevent slipping, and friction between B and the incline on which it slides is negligible. The cables in the pulley system are inextensible, and the coefficient of kinetic friction between crate A and the horizontal surface is μk. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Determine the required value of μk so that the speed of B is 7 m/s after it slides 5 m down the incline. (Round the final answer to four decimal places.) Required information
