A block rests at the top of a frictionless inclined plane as shown in the image. The inclined plane makes an angle of 26.2∘ with the horizontal direction. If the mass of the block is 1.00 kg and it begins from rest, how fast will the block be moving after it has traveled 0.772 m down the plane? Report your answer in m/s.

Two blocks, labeled A and B, are connected by a massless string that runs over a massless and frictionless pulley. Block A is sliding up along an inclined plane with ordinary surface friction. The string from block A runs over the pulley and then to block B which hangs straight down. At the start of the experiment, block A is sliding up the plane and block B is moving downward, both at a speed of v0 = 1.5 m/s. Block A has a mass of 3.3 kg. Block B has a mass of 1.4 kg. The plane is inclined at an angle of 27 degrees above horizontal. The coefficient of kinetic friction between block A and the plane is 0.36 (no units). Assume that the only significant forces on the blocks are normal forces, tensions forces, friction from the inclined plane, and gravity (with g = 9.81 m/s2 ). From the start of the experiment, when block A is sliding up the plane at a speed of 1.5 m/s, how far (in units of meters) does block A slide before coming to a stop? Just one more "show your work" after this one. You will need to submit your solution for this question.

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). (A)Calculate the magnitude of the acceleration (in m/s2) of the blocks as Block A is on the way UP its incline. 20.1 5.36 2.40 9.25 6.16 13.0 (B)Calculate the tension (in N) in the rope as Block A is on the way UP its incline. 233 95.9 43.0 110. 359 165 (C)Calculate the magnitude of the acceleration (in m/s2)of the blocks as Block A is on the way DOWN its incline. 15.0 9.70 1.79 4.60 4.00 6.90 (D)Calculate the tension (in N) in the rope as Block A is on the way DOWN its incline. 367 238 98.0 43.9 113 169 (E)Assuming the ramps and ropes are long enough, over what total distance (in meters) will the blocks have moved along their inclines after 3.5 seconds from start of the motion? (HINT: This is asking for distance, not displacement. ALSO, recognize that at some point over this 3.5 second time interval the blocks will stop and reverse direction.) 27.6 18.4 38.9 7.18 16.0 60.0
