A hot air balloon is travelling vertically upward at a constant speed of 3.7 m/s. When it is 27 m above ground, a package is released from the ballon. a) After it's released, for how long is the package in the air in units of s? Acceleration of gravity is 9.8 m/s/s. b)What is the speed just before impact with the ground in m/s? c) Now assume the hot air balloon is traveling vertically downward at a constant speed of 3.7 m/s. After the package is released, how long is it in the air in s? d) What is the speed just before impact with the ground in 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.
