Two friends are throwing basketballs from the main floor of a theatre to the balcony. One person stands exactly 4.0 m above the other person, and both release and catch the basketballs at the same height above their feet. The basketballs are always caught on their way down. The boy on the main floor releases his basketball with an initial velocity of 25 m/s [up]. With what velocity should the girl on the balcony throw her ball at the same moment, so that both basketballs will be caught by the other person at exactly the same time? show your work.
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.
