A Coast Guard ship is traveling at a constant velocity of 4.38 m/s, due east, relative to the water. On his radar screen the navigator detects an object that is moving at a constant velocity. The object is located at a distance of 3990 m with respect to the ship, in a direction 35.0° south of east. Six minutes later, he notes that the object's position relative to the ship has changed to 811 m, 51.0° south of west. What are (a) the magnitude and (b) direction of the velocity of the object relative to the water? Express the direction as an angle with respect to due west. (a) Number (b) Number 2.253 0 Units Units m/s : North of west :
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.
