Suppose a chinook salmon needs to jump a waterfallthat is 1.50 m high. If the fish starts from a distance 1.00 mfrom the base of the ledge over which the waterfall flows,(a) find the x - and y - components of the initial velocity the salmon would need to just reach the ledge at the top of itstrajectory. (b) Can the fish make this jump? (Note that a chinooksalmon can jump out of the water with an initial speedof 6.26 m/s.)
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.
