Wellington Wildcat is rushing to get to a parade in time to be the grand marshal. He’s standing in the back of a flatbed truck while McFogg the Dog races at 25 m/s towards town. Suddenly, McFogg sees a tiny maple leaf in the road 55 m ahead, and, being a proud Canadian, slams on the brakes to protect the sacred totem. Since McFogg is known to ride the brakes like a real jerk, let’s assume his reaction time to hit the breaks is essentially zero. A. Can McFogg actually stop before the truck reaches the leaf? The coefficients of friction between rubber tires and dry concrete are: μs = 1.00, μk = 0.80. When answering this question, be sure to include a free-body diagram representing the truck and its stellar mascots as a single object. B. Now here’s the real serious question: Is it possible for McFogg to stop short of the leaf such that Wellington does not slip and slide into the back of the truck cab? The coefficients of friction for Wellington’s shoes on the bed of the truck are: μs = 0.60, μk = 0.30. When answering this question, you should include a free-body diagram for the wildcat in peril
Displacement, Velocity and Acceleration
In classical mechanics, kinematics deals with the motion of a particle. It deals only with the position, velocity, acceleration, and displacement of a particle. It has no concern about the source of motion.
Linear Displacement
The term "displacement" refers to when something shifts away from its original "location," and "linear" refers to a straight line. As a result, “Linear Displacement” can be described as the movement of an object in a straight line along a single axis, for example, from side to side or up and down. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Non-contact sensors such as LVDTs and other linear location sensors can calculate linear displacement. Linear displacement is usually measured in millimeters or inches and may be positive or negative.
