A car bumper is designed to bring a 2,253-lb car to a stop from a speed of 4.9 mph while deforming 3.2 in. Assume constant deceleration and determine the average force on the bumper during this stop. (60 mph = 88 ft/sec). Assume all the kinetic energy of the car is converted by the work performed on the bumper Kinetic Eenergy = mv² Work=Fxd

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.
