A jet aircraft with a mass of 4,650 kg has an engine that exerts a force (thrust) equal to 60,700 N. (a) What is the jet's acceleration when it takes off? (Give the magnitude.) m/s2 (b)What is the jet's speed after it accelerates for 9 s? (Assume it starts from rest.) m/s (c) How far does the jet travel during the 9 s? m
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.
