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.

2) After playing a game of pinball, you decide to do some calculations on the launching mechanism. The pinball and the plunger have a mass of 0.30 kg and 0.50 kg respectively. The spring coefficient in the pinball machine is 300 N/m. The original length of the spring is 100 mm and the compressed length is 35 mm. If the coefficient of friction between the ball and the surface is 0.15, calculate the velocity of the ball right before it loses contact with the plunger (in m/s). Note that the plunger is never in contact with the ground and assume the ball slides without rolling. [Ans. to check: 1.23 m/s] HO www
