An object is thrown upwards with a speed of 13 m/s. How long does it take to pass through a height of 4.0 m above the initial on the way back down? Neglect air resistance. Hint: Straightforward freefall problem if you draw a good coordinate system and label it with the known data. Which root should you choose? O 1.2 s O 3.1 s O 2.3 s 4.2 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.
