(Continue) An astronaut drops a hammer from rest a vertical distance of 2.0 meters above the surface of the moon. If the acceleration due to gravity on the moon is a(t) = -1.62 . т (c) How fast is the rock when it hits the ground? O 2.333 m/s 2.364 m/s 1.887 m/s -2.545 m/s None of the above/below 1.634 m/s O 1.781 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.
