Jack throws a baseball straight up in the air as hard as he can! It takes 4.0 seconds to reach the top of its path. a. What was the speed, in m/s, of the ball as Jack released it? b. How high did the ball go? c. What was the instantaneous velocity of the ball at the top of its path? d. What was the acceleration of the ball at the top of its path? e. Create a quantitative v-t graph (use graph paper) for the ball for the upward motion (make upward be a positive velocity).
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.
