A skier jumps at 29.4 m/s. In the instant just before landing three seconds later, the magnitudes of the horizontal and vertical components of their speed are: a) 0 ; 29.4 m/s b) 29.4 m/s ; 0 c) 29.4 m/s ; 29.4 m/s d) 29.4 m/s ; 41.6 m/s e) 41.6 m/s ; 41.6 m/s
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.
