S2. While driving down the highway at 30 m/s, Bill spots a police car with sirens flashing behind him. The police car is also traveling at 30 m/s and is 100 meters behind Bill's car, when Bill floors the gas pedal, giving his car an acceleration of 2.0 m/s². Bill keeps the pedal floored for 5 seconds. During this time, the police car keeps moving at 30 m/s while the officer radios for backup. At the end of those 5 seconds, how much distance is between Bill's car and the police car? A. 125 m B. 80 m C. 160 m D. 250 m E. 275 m 11J 3
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.
