Smoky, the cat, is relaxing on the arm of a couch, 1m above the ground, when he is startled by something and jumps straight up in the air with an initial speed of 4 m/s. Coming down he missed the couch and lands on the ground. ( ignore air resistance) time to reach max height is .408 s max height is 1.816 m What is smoky's velocity just before he hits the ground? How long is Smoky in the air?
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.
