Show Solution

Two bodies of masses kg and kg are attached to the ends of a string. The first one is placed on a smooth inclined plane that makes an angle of with the horizontal, and the string passes over a small smooth pulley fixed at the top of the plane, where the other body is hanging vertically below the pulley. If the system starts moving form rest, and the gravitational acceleration , determine the acceleration of the system.

Two bodies having the masses of 33 and 45 kilograms are attached to the ends of a string passing over a smooth pulley fixed at a table's edge. The body of larger mass is placed on the table while the smaller one is hanging vertically below the pulley so that the horizontal part of the string is perpendicular to the table's edge. Determine the tension in the string, given that the gravitational acceleration .
