3. An airline passenger drops a coin while the plane is moving at 245.0 m/s. What is the velocity of the coin when it strikes the floor 1.652 m below its point of release: (a) Measured relative to the plane? (b) Measured relative to the Earth? (c) Find the vertical and horizontal displacement of the coin in the frame of reference of the Earth.
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.
