4. In this problem from the book we will break down
steps, doing part on each slide.
a. Write the original motion of the boat a a vector by
breaking that motion into components. You will
need to use a calculator to estimate sine and cosine
of 70 degrees (why 70 and not 20)? Decimal
answers are fine, but carry at least 2 decimal places.
