8. A person standing on a 25-m high ledge atop a cliff drops a rock. At the same time, another person at the base of the cliff throws another rock straight upward at a speed of 15 m/s. Assume that air resistance is negligible and g = 9.8 m/s?. How high from the base of the cliff will the two rocks meet? 11 m 14 m 18 m 23 m
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.
