I have tried to get this problem many different ways but still dont get it. A 1.00 kg aluminum block and a 8.00 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 = 40.0°) as shown in Figure P4.63. View attachment p4-63.bmp Figure P4.63 Making use of Table 4.2, determine the following. (a) the acceleration of the two blocks Your answer differs from the correct answer by 10% to 100%. m/s2 (b) the tension in the string N Coefficients of Frictiona µs µk Steel on steel 0.74 0.57 Aluminum on steel 0.61 0.47 Copper on steel 0.53 0.36 Rubber on concrete 1.0 0.8 Wood on wood 0.25-0.5 0.2 Glass on glass 0.94 0.4 Waxed wood on wet snow 0.14 0.1 Waxed wood on dry snow - 0.04 Metal on metal (lubricated) 0.15 0.06 Ice on ice 0.1 0.03 Teflon on Teflon 0.04 0.04 Synovial joints in humans 0.01 0.003 a All values are approximate.
