A ferry makes a short run between two docks; one in Lincoln Harbor, New Jersey, the other on W 34th street, NY. As the ferry approached W 34th street (travelling in positive x direction) its speed is 7.4m/s a) If the ferry slows to a stop in 12.3 seconds, what is its average acceleration? b) As the ferry returns to the Lincoln Harbor, its speed is 7.3m/s. If it comes to rest in 13.1 seconds, what is its average acceleration?
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.
