A cross-country runner has a speed of 3.30 m/s and runs in a direction 20.0° counterclockwise from the positive x-axis. (a) What are the components of the runner's velocity, in meters per second? x component y component m/s m/s (b) If the runner slows down until his speed is one quarter of the original speed, how will it affect the components of his velocity? O His velocity components will be quartered. O His velocity components will be quadrupled. O His velocity components will not change. O His velocity components will be halved.
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.
