The "reaction time" of the average automobile driver is about 0.7 ss . (The reaction time is the interval between the perception of a signal to stop and the application of the brakes.) An automobile can slow down with an acceleration of 13.2 ft/s2ft/s2 . A)Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 16.6 mi/hmi/h . (in a school zone) B)Compute the total distance covered in coming to a stop after a signal is observed from an initial velocity of 57.0 mi/hmi/h Give answers in ft
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.
