Two people are skating on ice. The first one skates by the second with a constant velocity of 12.0 m/s. The second person, not wanting to be left behind, begins at rest and then accelerates at a = 4.0 m/s2 in the direction of the first skater as soon as the first skater passes by. How far must the second skater skate before she catches up with the first skater?
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.
