At the equator, the radius of the Earth is approximately 6370 km. A jet flies at a very low altitude at a constant speed of v = 245 m/s. Upon landing, the jet can produce an average deceleration of a = 15.5 m/s2. How long will it take the jet, in seconds, to circle the Earth at the equator? t = What is the numeric value for the minimum landing distance, d (in meters), this jet needs to come to rest? Assume that when the jet touches the ground it is moving at the same speed as it was when it was flying. d =
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.
