n problem 11, if the dragstrip is ¼ mile, or 402.3 meters long, at the acceleration of 24.1 m/s2 , what is the time that the dragster records for his or her quarter mile run to two decimal places assuming uniform acceleration during the entire length of the track? What was the dragster’s final velocity in miles per hour (two decimal places) when it crossed the finish line and deployed its parachute?
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.
