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...

(26) A block of mass mi located on a horizontal frictionless surface is connected by a light non-stretchable cord that passes over a massless frictionless pulley to a second block of mass m2, which is allowed to move on an inclined friction- less plane of angle e, as shown in Fig. 5.37. Find the acceleration of the two blocks and the tension in the cord when mı = 2 kg, m2 =6 kg, sin 0 =4/5, and cos...

Two blocks with masses m1 and m2 are connected by a massless string over a frictionless pulley. Block 1 sits on a frictionless horizontal surface and block 2 sits on a plane inclined at an angle θ above the horizontal. The coefficient of friction between block 2 and the incline is µk. The pulley, which is a uniform disk, has a mass mp and a radius R. When you release the blocks, both blocks slide without the string slipping on...
