You throw a water balloon vertically downwards with a speed of 15 m/s from a height of 29 m above the ground. At the exact same time, your friend drops a water balloon from a height of 11 m above the ground at the same speed. (a) Which water balloon hits the ground first? Yours or your friend's? Use calculations to support your answer. (b) How much faster is your water balloon traveling when it hits the ground compared to the speed of your friend's water balloon when 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.
