A sprinter practicing for the 200-m dash accelerates uniformly from rest at A and reaches a top speed of 43 km/h at the 51-m mark. He then maintains this speed for the next 81 meters before uniformly slowing to a final speed of 35 km/h at the finish line. Determine the maximum horizontal acceleration which the sprinter experiences during the run. Where does this maximum acceleration value occur? Part 1 Answers: (a) latl= Finish line Calculate (a) the magnitude of the tangential acceleration near start of the race and (b) the magnitude of the tangential acceleration near the end of the race. (b) lal- m/s² 39.9 m m/s² A
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.
