Ball #1 is dropped from rest, and it takes t = 2.6s for it to reach the ground. Ball #2 is thrown upward with initial velocity v; and from the same height from which ball #1 was dropped. If ball #2 is airborne for twice as long as ball #1 before hitting the ground, then what is v₂?
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.

would 9.8 be negative in this scenario because it's falling to the ground?
