A rock is thrown directly up with an initial velocity of ???=20.2m/svoy=20.2m/s at instant ?A as shown in the figure below. As it moves up it will reach a certain height ℎ=12.3mh=12.3m at an instant ?B. It come back to the same height during it's fall from the maximum height at instant ?C. Determine the time it takes for the rock to go from ?B to ?C. Express your answer using one decimal place in units of seconds and take ?=9.81m/s2g=9.81m/s2.
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.
