The discussion clarifies the meaning of 50° SW in navigation, indicating it refers to 50 degrees South of West, which equates to 230°. Participants note that 50° NE would instead be a different angle. There is some confusion about the terminology, with one user suggesting that 50° could also be interpreted as 50 degrees West of South, which would be 220°. Ultimately, the consensus is that 50° SW is correctly understood as 230°. The conversation highlights the importance of precise directional terminology in navigation.

Hi!
My textbook has an answer written as 50° SW. I thought 50° was NE?...Does the book mean -50°(230°)?

Thanks!

Could be they mean 50° South of West, equivalent to 180° + 50° = 230°.

-50° would be equivalent to 310°.
 
OHHH south OF west haha I understand. Thanks!

Wouldn't that be 50 degrees West of South :-)

West is 270 degrees so 50 degrees South of West would be 220.
 
The book claims the answer is that all the magnitudes are the same because "the gravitational force on the penguin is the same". I'm having trouble understanding this. I thought the buoyant force was equal to the weight of the fluid displaced. Weight depends on mass which depends on density. Therefore, due to the differing densities the buoyant force will be different in each case? Is this incorrect?
