1. A stone is thrown vertically downward at an initial speed of 14 m/s from a height of 65 m above the ground. A) How far does the ball travel in 2.0 s? B) What is its velocity of the just before it hits 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.

2. Two balls are thrown vertically, both at the initial speed of 10.0m/s from a height of 60.0 m above the ground. Ball A is thrown upward, while ball B is projected downward. Which ball will hit the ground first?
