A heavy sled is being pulled by two people as shown in the figure. The coefficient of static friction between the sled and the ground is μs = 0.635, the coefficient of kinetic friction is μk = 0.405, and the combined mass of the sled and its load is m = 276 kg. The ropes are separated by an angle ϕ = 29∘, and they make an angle θ with the horizontal. Assuming both ropes pull equally hard, what is the minimum rope tension Tmin required to get the sled moving? Tmin =

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

Two blocks are connected by a massless string over a pulley, as shown at right. Block A has a mass of 20 kg, and Block B has mass m. The coefficient of static friction between Block A and the horizontal surface is μs = 0.30 and the coefficient of kinetic friction between Block A and the surface is μk = 0.20. The mass m of block B can be selected to be any value between 0 kg and 40 kg. The value of m is chosen, and the system is released from rest. This is repeated for many different values of m. 6) On the axes provided, graph the friction force Ff acting on block A vs. the mass m of block B. Note the value of important points on the graph such as discontinuities, maxima, and minima. Show your work.
