Question:

Help with vectors and bearings please!?

Hi, the question is; A fish swims 2km from point A to point B at a bearing of 30 degrees (measured anticlockwise from due east). It then travels due east to point C for 1km.a) Determine the distance the fish is from its starting point.b) Write vector AB and BC using vector units i and jI drew a diagram, and am completely stumped! thank you in advance! guidance in the right direction is also fine! I just have no idea where to start!

Answer:

using compass bearings: (2,60°) + (1,90°) = (2.9093, 69.8961°) - - - - - - (2,60°) = (1.7321, 1) - - - - - - (1,90°) = (1, 0) - - - - - - (1.7321, 1) + (1, 0) = (2.7321, 1) - - - - - - so: a) 2.9093 km b) (1.7321, 1) and (1, 0)
