A stone is thrown vertically upward with a velocity of 96 ft/s from the top of the tower 112 feet high. (above the ground) Ignore , air resistance Determine the equation of motion s(t) of the stone if the point of reference is the ground. A. s(t) = - 16t2 + 96t + 112 B. s(t) = - 16t2 + 96t - 112 C. s(t) = - 32t2 + 96t + 112 D. s(t) = - 16t2 + 96t
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.
