Dr. Dunn is sledding down a hill after a snowstorm. He starts at rest at A in the figure below. He passes through point B and stops some distance later at C. (a) What is the distance between points B and C? (b) How long does it take for him to stop after he passes point B? The coefficient of friction between his sled and the snow is μk = 0.1, and the total weight of the sled and rider is 130 lbs

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.
