Member advised to use the homework template for posts in the homework sections of PF.
Hi I am new the site and have to complete this physics summer work from a not so clear textbook. I am also new to a lot of the concepts and material. I was unsure on how i go about solving velocity a and b in this problem:

Hint: Look up 'sine rule'.

Forgot about the sine rule. Thank you!

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?
