A cargo ship makes a short run between two docks: one in Mock Town. The other is in Logue Town. As the ship approaches Logue Town, (traveling in the positive direction), its speed is 7.4 m/s. As the ship goes back to Mock Town, its speed is 7.3m/s. If it comes with rest in 13.1s, what is its average acceleration? a. 0.60 m/s2 b. -0.60 m/s2 c. 0.56 m/s2 d. -0.56 m/s2
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.
