- 1.2 m/s, y = 2.4 The position of a bird in the xy-plane is given by Btî + (yt-c t?)j where a = and B = -4.8 m/s. What is the bird's net acceleration at 2.0 s (magnitude and direction)? %3D O 2.4 m/s2 in the -y direction O 7.2 m/s? in the +y direction O 1.2 m/s2 in the +y direction O 7.2 m/s? in the -y direction O 5.4 m/s2 in the +y direction 5.4 m/s2 in the -y direction O 2.4 m/s? in the +y direction O 1.2 m/s2 in the -y direction
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.
