The archerfish hunts by dislodging an unsuspecting insect from its resting place with a stream of water expelled from thefish’s mouth. Suppose the archerfish squirts water with an initial speed of 2.30 m>s at an angle of 19.5° above the horizontal. When the stream of water reaches a beetle on a leaf at height h above the water’s surface, it is moving horizontally.a. How much time does the beetle have to react?b. What is the height h of the beetle?c. What is the horizontal distance d between the fish and the beetle when the water is launched?
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.
