  2. Two blocks attached by a string slide down a 10° incline. Block 1 has mass m1 = 0.80 kg and block 2 has mass m2 = 0.25 kg. In addition, the kinetic coefficients of friction between the blocks and the incline are 0.30 for block 1 and 0.20 for block 2. Find (a) the magnitude of the acceleration of the blocks, and (b) the tension in the string.

  3. An object of mass m1 on a frictionless horizontal table is connected to an object of mass m2 through a very light pulley P1 and a light fixed pulley P2 as shown. If a1 and a2 are the accelerations of m1 and m2, respectively, what is the relation between these accelerations? • Express the tensions in the strings and the accelerations a1 and a2 in terms of the masses m1, and m2, and g.
