In which one of the following situations does the car have an acceleration that is directed due north? Select one: a. A car is traveling northward as its speed decreases from 24 m/s to 18 m/s. b. A car travels southward with a constant speed of 24 m/s. C. A car is traveling southward as its speed decreases from 24 m/s to 18 m/s. d. A car is traveling southward as its speed increases from 24 m/s to 33 m/s. e. A car travels northward with a constant speed of 24 m/s. Clear my choice
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.
