A stone is dropped from rest from the top of a high-rise. It takes △t = 2.6 s for it to reach the ground. a. What is the initial velocity, Vi, of the stone in m/s? b. What is the value of the magnitude of acceleration, in m/s^2?? c. Express the final velocity vf of a object travelling with an acceleration a for a time period △t which starts with an initial velocity vi. d. Calculate the magnitude of vf in 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.
