A steel ball is dropped from a building's roof and passes a window, taking 0.117 s to fall from the top to the bottom of the window, a distance of 1.22 m. It then falls to a sidewalk and bounces back past the window, moving from bottom to top in 0.117 s. Assume that the upward flight is an exact reverse of the fall. The time spent below the bottom of the window is 1.90 s. How tall is the building
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.
