Question

Note: The left-hand mass is equal to the sum of the other two masses.

A massless pulley is attached to the ceiling,in a uniform gravitational field, and rotates with no friction about its pivot. Another massless pulley is attached to the end of the
cord on the right and rotates with no friction about its pivot.

The acceleration of gravity is 9.8 m/s2 .
