Situation 2: A stone is thrown upward from the ground with a velocity of 60m/sec. Four seconds later, another stone is thrown vertically into the air. (a) Determine the time that the first stone has traveled in order to meet the second stone 120 meters from the ground. (b) What initial velocity must the second stone have in order to meet the first stone 120m from 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.
