- A 17 kg block rests on a 32 degree inclined frictionless surface and is attached by a light string to a 34 kg hanging mass where the string passes over a massless frictionless pulley. If g = 9.8 m/s2, what is the tension in the connecting string?A magnet of mass 6.32 kg is suspended from the ceiling by a cord as shown. A large magnet is somewhere off to theright, pulling on the small hanging magnet with a constant force of F = 113.4 N. At what angle theta ?with respect to thevertical does the magnet hang? A) 33.4 degreesB) 61.3 degreesC) 28.7 degreesD) 27.0 degreesTwo identical strings making an angle of = 30.0 with respect to the vertical support a block of mass m = 15.0 kg (Fig. P4.32). What is the tension in each of the strings?

- a hanging lamp of weight 50 N hangs from a chord that is knotted at point O to other chords, one fastened to the ceiling and the other to the wall. We want to find the tension in three chords, assuming the weight of the chords to be negligibleA m1 = 1.50-kg aluminum block and a m2 = 6.10-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 θ = 32.0°) as shown in the figure. (For aluminum on steel, μs = 0.61 and μk = 0.47. For copper on steel, μs = 0.53 and μk = 0.36.)I just helped someone solve this yesterday but I cant remember what I needed to do to get the answer, give me some help? It's the 3 box problem where the 80kg box is in the middle and the 25kg to the right and 10kg to left with frictional coefficient of 0.1 it asks for the acceleration of the system and the tension in the wires.
