At 10:11 a.m., you pass a speed radar on the freeway. At 10:31 a.m., you pass a second speed radar along the same freeway. If the second radar was located 18 miles from the first radar, and the speed limit along the entire stretch of highway is 70 mph, could you be fined for speeding based on the radar data? Find your average velocity in miles per hour (note: 20 minutes = 1/3 hour) from 10:11 a.m. to 10:31 a.m. Round to 2 decimal places if needed.
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.
