Concept explainers

Basic Terminology in Mechanics

The area of science and mathematics concerned the motion of the objects, the relation between the force matter, and motion if specified. Forces exerted over the objects result in displacements or changes in the position of an object concerning its environment. This branch of physics keeps its roots in Ancient Greece in the form of the scripts of Aristotle and Archimedes.

Question

The system shown in Figure 2 is at rest
when the lower rope is cut. Determine the
speed of the objects when they are at the
same height on the pulley. There is no
friction and their mass is negligible.
