A celebrated Mark Twain story has motivated contestantsin the Calaveras County Jumping Frog Jubilee, wherefrog jumps as long as 2.2 m have been recorded. If a frogjumps 2.2 m and the launch angle is 45°, find (a) the frog’slaunch speed and (b) the time the frog spends in the air.Ignore air resistance.
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.
