Two masses `m_(1)` kg and `m_(2)` kg passes over an atwoods machine. Find the ratio of masses `m_(1)` and `m_(2)` so that string passing over the pulley will just start slipping over its surface. The friction coefficient between the string and pulley surface is 0.2.

Two masses m_(1) and m_(2) are connected to the ends of string passing over a pulley. Find the tension and the acceleration associated.

A situation is shown in figure-2.15, Find the acceleration of masses m_(1) abd m_(2) mass of pulley is m_(P) . Consider the string going over the pulley is massless and frictionless.

If two masses m_1 and m_2 (m_1 gt m_2) tied to string moving over a frictionless pulley, then acceleration of masses

two masses 2m and m are attached to the the ends of a string while passing over a smooth Pulley of mass m and radius R . The ratio of tensions in both the strings is

Two blocks of masses M_(1)=4 kg and M_(2)=6kg are connected by a string of negligible mass passing over a frictionless pulley as shown in the figure below. The coefficient of friction between the block M_(1) and the horizontal surface is 0.4. when the system is released, the masses M_(1) and M_(2) start accelrating. What additional mass m should be placed over M_(1) so that the masses (M_(1)+m) slide with a uniform speed?
