A sky lantern which a child tied to a piece of stone on the ground at the side of a tall multi- storey building got loose and then rose vertically upward with a uniform rate of 2.7 m/sec. At a certain height, it touched a small loose stone on the side of the building. The stone strikes the ground after 2.5 sec. Determine the height in meters of the sky lantern when the stone touched the ground.

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.
