Lesson: Applications of Newton’s Second Law: Two Masses Hanging from a Pulley Mathematics
In this lesson, we will learn how to solve problems on the motion of a system of two bodies suspended vertically by a string passing over a smooth pulley.
Two bodies of masses 12 kg and 18 kg are attached to the ends of a light inextensible string which passes over a smooth pulley. Determine the acceleration of the system. Take .
Two masses and 88 g are attached to the ends of a light string passing over a smooth pulley. Determine the value of , given that, when the system was released, the other mass descended 11.76 m in 2 seconds. Take the acceleration due to gravity .
Two masses of 143 g and 77 g are connected to the ends of a light inextensible string passing over a fixed smooth pulley. Given that the two masses were hanging freely vertically below the pulley and that the system was released from rest, find its velocity 4 seconds later. Take .
