A seagull flies at a velocity of 12.5 m/s relative to the air straight into the wind. vSA = 12.5 m/s t = 16 min d = 5.8 km 1. If it takes the bird 16 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive. 2. If the bird turns around and flies with the wind, how long, in minutes, will it take to return 5.8 km?
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.
A seagull flies at a velocity of 12.5 m/s relative to the air straight into the wind.
vSA = 12.5 m/s
t = 16 min
d = 5.8 km
1. If it takes the bird 16 min to travel 5.8 km relative to the Earth, what is the velocity of the wind, in meters per second, relative to the Earth? Take the direction of travel of the seagull to be positive.
2. If the bird turns around and flies with the wind, how long, in minutes, will it take to return 5.8 km?
