A certain hawk can fly horizontally (i.e., not diving) at a maximum speed of 80.0 km/hr The hawk can decelerate at a much higher rate of 2.75 m/s2 . a. If initially flying at its top speed, how much time does it take for the hawk to come to a stop? b. How far does it travel during this time? c. If the hawk has a mass of 1.1 kg, what is the average force that must be applied by its wings in order to come to a stop?
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.
