A dolphin in an aquatic show jumps straight up out of thewater at a velocity of 13.0 m/s. (a) List the knowns in thisproblem. (b) How high does his body rise above the water?To solve this part, first note that the final velocity is now aknown and identify its value. Then identify the unknown, anddiscuss how you chose the appropriate equation to solve forit. After choosing the equation, show your steps in solving forthe unknown, checking units, and discuss whether the answeris reasonable. (c) How long is the dolphin in the air? Neglectany effects due to his size or orientation
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.
