An object is moving off a roof with the velocity of 7 m/s as shown in the below figure. a) How far from the edge of the house does the object hit the ground? b) Draw 4 graphs showing the change of positions and velocities over time in horizonal axis and vertical axis, respectively, for the object motion in question a). c) There is a person standing 4 m from the edge of the house. Will the object hit him given his height is 1.9 m? 40° Vo = 7.00 m/s 14.0 m 40m Page 2 of 3 к
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.
