Joe Biden feebly pushes a box of his successful accomplishments up a long 20° frictionless incline toward Nancy Pelosi who waits at the top. If the box was given an initial speed of 3 m/s up the incline, how much time does it take the box to rise, stop and return to its starting position? A) 0.55s B) 1.79s C) 2.69s D) 1.06s E) 1.43s
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.
