Rasberry Crazy Ants, a species found in wall sockets, cellphones, and television sets are slowly spreading across Texas and are poised to spread across the entire South. Named for Texas exterminator Tom Rasberry, who spotted ants moving in an erratic swarm in 2002, the destructive ants are now in 23 counties in Texas, the Austin American-Statesman recently reported. Although their march in inexorable, it is also quite slow. They travel at an average speed of 1.8 feet per day. At that rate, how long will the swarm that is presently centered in Austin, Texas, take to reach Boston?

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.
