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.

To be able to use the conservation of energy on a moving body to determine key characteristics about the mechanics of the system. A package of mass m= 1.00 kg is pushed across the surface by a jet of compressed air during an assembly-line process. The package is moved through a distance of s = 47.0 cm. The package and the surface are known to have a coefficient of kinetic friction of μk= 0.15. The package is initially at rest for this process. If the package must be moving at a speed of v = 17.0 cm/s when it has reached the distance of 47.0 cm, determine the average force that the jet of compressed air must supply to the package If it is now desired that the package be at rest when it has reached the distance of 47.0 cm , determine the average force that the jet of compressed air must supply to the package if the package is initially traveling in the s direction at a velocity of v = 13.5 cm/s If the plant has changed the mass of the package on the assembly line to m = 1.35 kg ,…
