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.

A cylinder of radius 7 = 0.2 m is about to start rolling down an inclined plane. The acceleration of the center of the cylinder is 9.81 sin(0) m/s?. The angular acceleration is 9.81 sin(0)/r rad/s?. Assume 0 = 0.8 rad. What is the magnitude of acceleration of the point on the cylinder furthest from the inclined plane in m/s?. Hint: Since it is about to start rolling, the velocity of the center of the cylinder and angular velocity of the cylinder are still zero at that instant.
