10- A toy racing car moves with constant speed around the circle shown below. When it is at point A its coordinates are x = 0, y = 3m and its velocity is (6m/s) i. When it is at point B its velocity and acceleration are: A. -(6 m/s) j and (12 m/s) i, respectively LA B. (6 m/s) i and -(12 m/s) i respectively C. (6 m/s) jand (12 m/s) i, respectively D. (6 m/s) j and (2 m/s) j, respectively B E. (6 m/s) j and 0i, respectively
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.
