H.W: Two boxes are connected by a cord running over a pulley. The
coefficient of kinetic friction between m1 (5kg) and the table is 0.20. We ignore the
mass of the cord and pulley and any friction in the pulley, which means we can
assume that a force applied to one end of the cord will have the same magnitude at
the other end. We wish to find the acceleration, a, of the system, which will have the
same magnitude for both boxes assuming the cord doesn't stretch. As m2 (2Kg) move
down, mi move to the right.

held by three identical springs with force constant k = 100 Nm', as shown in Fig. A7.

motion, and determine the frequency of oscillation.
Consider the system below consisting of a rough surface, three masses, a massless string, and a massless and
frictionless pulley. The mass of each block is m. = 12.5 kg, mb = 15.0 kg, and m. = 13.5 kg.
