A sprinter accelerates from rest to a velocity of 12 m/s in the first 6 seconds of the 100-meter dash. a. How far does the sprinter travel during the first 6 seconds? b. How much farther does the sprinter have to travel to reach the finish line? c. If the sprinter travels at a constant velocity of 12 m/s for the last 64 m, how long will it take to reach the finish line?
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.
