An object fall from rest, and s = -16t^2 where s feet is the distance of the object from the starting point at t seconds, and the positive direction is upward. If a stone is dropped from a 256 ft. high building, find: a. The instantaneous velocity of the stone 1 second after it is dropped; b. The instantaneous velocity of the stone 2 second after it is dropped; c. How long it takes the stone to reach the ground; d. The instantaneous velocity of the stone when 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.
