The speed of current towards the east, vc = 2.0 m/s
The speed of kayaker, vk = 3.0 m/s
Let the angle from the perpendicular be θ.
A kayaker needs to paddle north across a 100-m-wide harbor. The tide is going out, creating a tidal current that flows to the east at 2.0 m/s. The kayaker can paddle with a speed of 3.0 m/s.
a. In which direction should he paddle in order to travel straight across the harbor?
b. How long will it take him to cross?
