Daryl and Cynthia leave home at 7 am, heading in opposite directions for work. Cynthia usually spends 20 minutes biking to work while Daryl needs only 30 minutes to walk to work. Cynthia's average speed is 3 miles per hour faster than Daryl's average speed. If they work 6 miles apart, what is the average speed, in miles per hour, for each person?
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.
