Block B, with mass 5.00 kg, rests on block A, with mass 8.00kg. There is no friction between the table and block A, but the coefficient of static friction between block A and B is 0.750. A "massless" string attached to block A passes over a frictionless pulley and block C is suspended from the other end of the string. If we want ALL the blocks moving together with the same acceleration, the largest possible mass that block C can...

Forces and Newton's LAWS WU PHYS 1107 - General Physics I ) An 9.0 kg mass (M) is placed on a horizontal surface. A massless rope runs over a frictionless massless pulley which connects the mass M to a 6.5 kg mass (m) that hangs vertically. a) What is the acceleration of the vertical mass if the horizontal surface is frictionless? b) What is the tension in the rope if the horizontal surface is frictionless? Now assume that the horizontal...

Block A in the figure has mass mA = 4.20 kg, and block B has mass mB = 2.40 kg. The coefficient of kinetic friction between block B and the horizontal plane is μk = 0.520. The inclined plane is frictionless and at angle θ = 34.0°. The pulley serves only to change the direction of the cord connecting the blocks. The cord has negligible mass. Find (a) the tension in the cord and (b) the magnitude of the acceleration...
