The river boat problem in 2D relative motion is a classic problem that involves analysing the motion of two objects, such as a boat/swimmer and a riverbank, in two-dimensional space.
The problem typically involves calculating the relative motion of the boat/swimmer with respect to the riverbank, considering factors like velocity and time. To solve this problem, we use vector addition, decomposition, and projection techniques by breaking down the motion into x and y components, then apply the relevant equations of motion to calculate the relative position, velocity, and crossing time of the boat.
*Bonus: it calculates accurately the launch angle when river velocity is greater than boat/swimmer velocity.
