A rocket is being launched. After a while, it rises at a constant velocity of 5 miles per second. An observer is standing 15 miles from the launching site. How fast is the distance between the rocket and the observer changing when the rocket is at a height of 8 miles? Present your answer as an approximation, accurate up to three or more decimals. _______ miles per second
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.
