A helicopter carrying Dr Evil takes off with a constant upward acceleration of 5 m/s2. A secret agent, Austin Powers, jumps on just as the helicopter lifts off the ground. After the two men struggle for 10 s, Powers shut off the engine and steps out of the helicopter. Ignore the effects of air resistance. (a) Find the maximum height the helicopter reaches. (b) Powers deploy a jet pack, 7 s after leaving the helicopter, which gives him a constant downward acceleration of 2 m/s?. How far above the ground Powers is 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.
