17. An object falls from a high building. Ignoring air resistance, what will its velocity be after 6 seconds of falling? Hint: Use the equation of motion; Final Velocity Vf = Vi + at ( Here, a = acceleration due to gravity = g = - 9.8 m/s2, t = 6 s, and the initial velocity, Vi = 0 m/s). So find Vf by using the formula, Vf = Vi + at O 9.8 m/s O - 9.8 m/s O 59 m/s 59 m/s
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.
