Mike is at rest. Glen is driving towards him at a speed of 15 m/s. Mike starts accelerating at a constant acceleration of 3 m/s^2, 1 second after Glen passes him. What is Mike's displacement when he passes Glen? What is Mike's velocity at the instant he passes Glen? Draw a position vs time graph and a velocity vs. time graph for both vehicles. How does Mike's average velocity during the pursuit compare to Glen's constant velocity?
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.
