2. During construction of the new large apartment building in Midtown, a piece of glass fell from the top of the building. The glass crashed onto the busy 57th street sidewalk below and injured 3 people. The new apartment complex has a height of 426 meters. Suppose the glass fell from the top of the building at rest. a. Ignoring air resistance, how long would it take the piece of glass to hit the ground? b. Ignoring air resistance, what will the velocity of the piece of glass be when it strikes the ground?
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.
