A very strong, but inept, shot putter puts the shot (ball) straight up vertically with an initial velocity of 15.0 m/s. The shot was released at a height of 2.20 m, and they are 1.60 m tall. a. How high does it rise above its starting point? b. What is the magnitude of its velocity at the highest point? c. What is the magnitude of its acceleration at the highest point? d. What is the direction of its acceleration at the highest point? e. How much time does he have to get out of the way before getting hit in the head by the shot (ball)?
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.
