A bearing of 60 degrees East of North.
Thank you oh great one.. Thank you very much
oh I'm new here and also new to physics..
I've drawn the diagram but Idk what scales to use cause how they using Knots and time in hours, and they also stating the conversion from knots to km/hr. I've tried a lot of assumptions but I just don't seem to get a right answer.
Scalar and Vector HELP please
A boat is traveling on a bearing of 25 degrees east of north at a speed of 5 knots ( a knot is 1.852km/hr). After traveling for 3 hours, the boat heading is changed to 180 degrees and it travels for a further 2 hours at 5 knots. What is the boat's bearing from its...
