A sprinter starts a race with an acceleration of 3.60 m/s^2. If the sprinter accelerates at that rate for 17.0m and then maintains that velocity for the remainder of the 100-m dash, what will be his time for the race? a. How long does it take the sprinter to run the first 17.0 m? b. What is the sprinters time for the race?
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.
