Vector subtraction works similarly to addition when you use components. For example,
(5, 3) minus (2, 1) equals 5 minus 2, and 3 minus 1; the result is the vector (3, 2).
A + B = (Ax + Bx,Ay + By)
AíB = (AxíBx,AyíBy)
A,B = vectors
Ax,Ay = A components
Bx,By = B components
The boat has the velocity A in
still water. Calculate its velocity
as the sum of A and the velocity
B of the river's current.
v = A + B
v = (3, 4) m/s + (2, í1) m/s
v = (3 + 2, 4 + (í1)) m/s
v = (5, 3) m/s
