You row a boat perpendicular to the shore of a river that flows at 3.0 m/s. The velocity of your boat is 4.0 m/s relative to the water.(adsbygoogle = window.adsbygoogle || []).push({});

a. What is your velocity of your boat relative to the shore?

b. What is the component of your velocity parallel to the shore? Perpendicular to it?

A was very easy... If you draw it out, you can easily see that it's a 3,4,5 triangle, so the answer to A is 5 m/s.

I'm not sure how to work out B. Which number do I use to find the components? Would the parallel to the shore component be 4 m/s? Would the perpendicular be 3 m/s? I'm not sure.. Or is it totally different numbers? Help with part B please.
