A river has a steady speed of 0.42 m/s. A student swims upstream a distance of 1.3 km and swims back to the starting point. a. If the student can swim at a speed of 1.01 m/s in still water, how long does the trip take? mins (round off to the nearest minute) b. How much time is required in still water for the same length swim? mins (round off to the nearest minute)
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.
