A helicopter carrying Dr. Doofenshmirtz takes off with a constant upward acceleration of [5.0 m/s2]. Secret agent Perry the Platypus jumps on just as the helicopter lifts off the ground. After the two men struggle for 10.0 [s], Powers shuts off the engine and steps out of the helicopter. Assume that the helicopter is in free fall after its engine is shut off. (a) What is the maximum height above ground reached by the helicopter? (b) Perry deploys a jet pack strapped on his back 7.0 [s] after leaving the helicopter, and then he has a constant downward acceleration with magnitude 2.0 [m/s2]. How far is Perry above the ground when the helicopter 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.
