(6) A ball is projected with initial velocity v=8i+6j m/s from the roof -81+6j m/s A of a building where it just passes the top of the wall (see fig.4) and falls to ground a distance 40 m from the wall. What is the height of the wall? A) 1.8 m B) 125 m C) 123.2 m D) 3.6 m 0 <<- x=40m Fig.4 B
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.
