יע BEEALIVE Since 1904 A 2.75-kg clay ball is fired horizontally at a hanging sign like the one shown above. The sign is 60 cm wide, 75 cm tall, 4 cm thick, and has a mass of 13.7 kg. The clay hits and sticks to the center of the bottom edge of the sign, and then the combination swings up about 7° from the rest position. Find the speed of the clay just before it hits the sign.

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.
