An electrician is working at the top of a ladder that is 16ft long and leaning against the wall when its bottom starts sliding at a rate of 1ft/s. Fortunately, a fellow worker catches it when the ladder’s bottom is 7ft from the wall. At what speed is the top of the ladder (along with the electrician) sliding down the wall at that instant? Round any intermediate calculations, if needed, to no less than six decimal places, and round your final answer to two decimal places.
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.
