A hot-air balloon is rising straight upward with a constant speed of 6.5 m>s. When the basket of the balloon is 20.0 mabove the ground, a bag of sand tied to the basket comes loose. (a) How much time elapses before the bag of sand hitsthe ground? (b) What is the greatest height of the bag of sand during its fall to 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.
