RS, a light frictionless pulley, and connecting ropes is shown in the figure. The B block has a mass of 9.3 kg and is on a perfectly smooth horizontal table. The surfaces of the A block, which has a mass of 8.2 kg, are rough, with uk = 0.25 between the block and the table. If the C block with mass 9.9 kg accelerates downward when it is released, find its aceleration.

A 9.80-kg hanging object is connected by a light, inextensible cord over a light, frictionless pulley to a 5.00-kg block that is sliding on a flat table. Taking the coefficient of kinetic friction as 0.218, find the tension in the string. (The block slides to the right in the diagram below.) N m₁ mą

A huge pendulum is made out of a 8.26-m cable attached at the top to a steel beam. The bottom of the cable is attached to a 38.7-kg anvil that swings back and forth. At the very bottom of its swing, the anvil travels at a speed of 2.53 m/s. Find the tension (in N) in the cable. (You may assume that the cable itself has negligible mass.)

You are playing stuffleboard and you must slide your weighted disk 8m across the floor where it will come to rest on the target. You give it an initial push of 4 m/s but then it slides on its own to a stop. The disk is 0.8 kg. What is the coefficient of friction if your shot is perfect a bull's eye?

Find the tensions in the two cords and the accelerations of the blocks as shown in the figure iffriction is negligible. The pulleys are massless and frictionless, mı=215g,m2=500g and m3=365g. m2 m3

Two ideal pulleys (massless and frictionless) form a pulley system that can lift a weight by pulling on the end of a massless rope, as shown below. The upper pulley is attached to the ceiling at point A, and the lower pulley is connected to a box of mass M = 10.0kg. (a) What is the tension in the rope if the box is accelerating upwards with a = 2.00 m/s^2? (b) What is the tension force at point A at the ceiling?

A cord passing over a pulley connects two masses, as shown, where m, = 3.60 kg and m, = 7.10 kg. The system accelerates with a magnitude of 1.34 m/s?. The coefficient of kinetic friction between the masses and the incline is the same for both masses. Assume the pulley is frictionless, and the cord is massless. (Due to the nature of this problem, do not use rounded intermediate values in your calculations-including answers submitted in WebAssign.) m2 m, 35.0° 35.0° (a) What is the coefficient of kinetic friction? (b) What is the tension (in N) in the cord?

A m1 = 1.65-kg aluminum block and a m2 = 6.05-kg copper block are connected by a light string over a frictionless pulley. The two blocks are allowed to move on a fixed steel block wedge (of angle ? = 34.0°) as shown in the figure. (For aluminum on steel, ?s = 0.61 and ?k = 0.47. For copper on steel, ?s = 0.53 and ?k = 0.36.)

Answer the question correctly. Thank you!

A 10 m long board that has a mass of 20 kg is held up by two vertical ropes. The left rope is 2 m from the left end of the board, and the other rope is 2 m from the right end of the board. A 40 kg box sits 2 m from the right end. Find the tension in the rope on the left.
