An incompetent batter hits a ball straight up with a velocity of 16.8 m/s. The equally incompetent catcher isn't paying attention to the pitcher must run to catch the ball from his mound 18.4 m away. Determine the time of flight of the ball and then determine what must the acceleration (assumed to be constant) of the pitcher be to catch the ball as it returns to its initial height?
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.
