a stone is dropped from the deck of a bridge. the sound of the splash reached the deck 3 seconds later. the speed of sound is 342 m/s in still air. a) what is the time the stone travels from the deck to the water surface before the splash? b) what is the height of the deck above the water surface? c) determine the time that the sound travels from tge water surface up the deck after the splash?
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.
