A stone is dropped from the deck of a bridge. The sound of the splash reached the deck 3 secs later. The speed of sound is 342 m/s in still air. Which of the following gives the time that the sound travels from the water surface up the deck after the splash? A 0.119 secs B 0.911 secs 11.91 secs D 10.19 secs E) 1.191 secs F) 9.110 secs
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.
