1. A stone is thrown vertically upward from the ground with a velocity of 15 m/sec. One second later, another stone is thrown vertically upward with a velocity of 30 m/sec. a. When will the stones be at the same level? Ans. t = 1.4 sec b. How far above the ground will the stones be at the same level? Ans S =11.4 m c. Determine the time the second stone travelled until the stones are at the same level?
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.
