A private jet carrying Parker takes off with a constant acceleration of 5 m/s^2. Romanoff jumps on just as the jet plane lifts of the ground. They took a flight 10 seconds on the jet then suddenly rhe Romanoff shuts the engine off and jumps out of the jet. The instant the engine shut down; the jet is assumed in free fall. Romanoff deploys a jet pack 7s after leaving the helicopter with a constant downward acceleration of 2 m/s^2. How far is Romanoff above the ground when the jet crashes into 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.
