Usain Bolt wants to complete a10kilometer-run in less than30 minutes.After running at constant speed for exactly26 minutes, the runner still has1.5kmleft to run.The runner must then accelerate at0.30m/s2for how many seconds to reach a final velocity that will allow them to complete the1.5kmleft of the race in the desired time?
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.
