Problem 7 A "moving sidewalk" in an airport terminal building moves at a speed of 1.3 m/s and is of length 37.0 m. A woman steps on at one end and walks at a speed 1.8 m/s relative to the moving sidewalk. a) How much time does she require to walk from one end to the other if she walks in the same direction the sidewalk is moving? b) How much time does she require to walk from one end to the other if she walks opposite to the direction the sidewalk is moving?
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.
