In a movie, the FBI is investigating an assassination attempt on the life of the president. The setting is a parade in New York, and an amateur photographer has made a videotape of the passing motorcade. A careful examination of the tape shows in the background a falling object that turns out to be a pair of binoculars used by the would-be assassin.From the tape the FBI is able to determine that the binoculars fell the last 12 m before hitting the ground in 0.38 s. It is vital to them to know the height,and hence the building floor, from which the binoculars were dropped. Can this be determined from the given information? if so, from what height were the binoculars dropped?
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.
