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.
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.
