A stone was dropped from a balloon which is ascending at a rate of 6 m/s when the balloon was 70m above the ground. a. Which of the following gives the velocity of the stone after 3 seconds? b. Determine the time required for the stone to attain a downward velocity of 15 m/s. c. What is the altitude of the stone from the ground after 4 seconds? d. How long did it take the stone to hit 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.
