roblem: Often times in football a punter may not need to kick the ball very far, but rather kick the ball high so that the other players have a lot of time to run down and make a tackle. If a punter punts a ball from 1.5 m high with an initial velocity of 25 m/sec an angle of72∘ to the horizontal, what are the maximum height and time of flight for the ball? Assume the ball lands on the ground.
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.
