Sky and Wayne decided to run 3 km on a straight road. According to the tracking app, Sky was running constantly at 7’36”/km while Wayne is running constantly at 6’42”/km. a. How far apart are they after 15 mins? b. After 15 mins since the run started,Wayne felt tired and decided to decrease his pace to 9’55”/km while Sky kept his pace at 7’36”/km. Who will reach the finish line first and by how much time is the person ahead of the other?
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.
