Example 1: IB = 2.04 s YB = 20.4 m VyB %3D A stone thrown from the top of a building is given an initial velocity of 20.0 m/s straight upward. The building is 50 m high. Using ta = 0 as the time the stone leaves the throwers hand %3D 4 = 0 YA = 0 O© c = 4.08 s Jc = 0 v,c = -20.0 m/s VyA V,a = 20.0 m/s %3D %3D at position A, determine:. (a) The time at which the stone returns to the position from which it was thrown. (b) The velocity of the stone at this instant O 6 = 5.00 s 50.0 m Yo = -22.5 s V,D = -29.0 m/s %3D lE = 5.83 s JE = -50.0 m © vE = -37.1 m/s %3D
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.
