A rock is dropped from the top of a building. Rock starts from rest and it takes 7seconds to reach the ground. How far did the rock travel in in 7 seconds? Use g = 9.8m/s2 (don't round the answer). Choose correct answer with the correct unit. A. 34.3 m B. 240.1 m/s C. 240.1 m D. 34.3 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.
