A dog running in an open field has components of velocity vỵ = 2.6m/s and v, = -1.8m/s at t = 10.0s. For the time interval from tį = 10.0s at t, = 20.0s, the average acceleration of the dog has magnitude 0.45m/s' and direction 31.0° measure from the +x-axis toward the +y-axis. At t = 20.0s, a. What are the x- and y- components of the dog's velocity? b. What are the magnitude and direction of the dog's 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.
