A fish swimming in a horizontal place has velocity v, = (4.01 + 1.0j)m/s at a point in the ocean where the position relative to a rock is í, = (10.0 – 4.05)m. After the fish swims with constant acceleration for 20 sec its velocity is v = (20.01 – 5.05)m/s. A) What are the components of the acceleration? B) What is the direction of the acceleration with respect to unit vector f? C) If the fish maintains constant acceleration, where is it at t=2.5 s, and in what direction is it moving?
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.
