28. A coin is tossed upward from the edge at the top of a tall building with a height of 150 [m] from the ground at a speed of 5.00 [m/s]. What is the speed of the coin when it reaches 130 [m] from the ground? A. -20.4 [m/s] C. -10.4 [m/s] B. L0.4 [m/s] D. 10.4 [m/s]
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.
