3. A stone is thrown off the edge of a cliff that is 16.0 m tall with an initial horizontal velocity of 90 m/s. a. How long does it take for the stone to fall? b. How far from the base of the cliff does it hit the ground? 4. A marble is thrown from the counter with a velocity of 4.7 m/s. The marble fall 1.8 m away the counter. a. Determine the height of the counter? b. What is the final velocity of the marble before it reaches the ground?
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.
