Solution 8.6b
From Mechanics
Here we use
in the first part.
According to the text
We assume the starting point is the origin so that
At
10=35i−30j=(7i−6j)
5
The distance is the magnitude of this vector
72+
−6
2=
13=3.6 m
In the second part the boat travel with constant velocity
Thus during the first part the boat has travelled a distance 3.6 m.
