isaacphysics help! pre uni physics B2.3
a) In which direction would I have to travel in order to travel North (relative to a stationary observer) if I am swimming in a river with a current running 0.4 m/s to the east, and i can swim 1.5m/s relative to the water? give your answer as a bearing degrees clockwise from north and to 3sf.
- i am so confused what does it mean by 'what direction' should i try trig? but which direction would the 1.5m/s go since its 'relative' to water?

The flow of water is a vector relative to the stationary observer.
The swimmer is swimming at a vector relative to the water.
So the vector of the swimmer relative to the stationary observer is the sum of those vectors.
The first step will be to sketch a vector triangle, have you done that yet?

Are you doing the mentoring scheme on Isaac?
