An object is shot straight up from the ground with an initial velocity of 20 m/s. How high above the ground is the object one second after it reaches its maximum height? Neglect air resistance." I got the maxiumum height of 20.41 m but I used it into the y(t) = y0 + v0t - 1/2gt^2 equation and I don't think I got it righ
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.
