A spy in a speed boat is being chased down a river by government officials in a faster craft. Just as the officials' boat pulls up next to the spy's boat, both reach the edge of a 7.3 m waterfall. If the spy's speed is 11 m/s and the officials' speed is 27 m/s, how far apart will the two vessels be when they land below the waterfall?
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.

Time taken by both boats to fall through height 7.3 m is same as their initial velocity in vertical direction is zero and acceleration is same
Time taken = = 1.21s
Relative velocity of boats = 27-11 = 16 m/s
Therefore distance of separation = 1.21*16 = 19.36 m
