Does anyone know where I can get practice problems on kinematics and 2D motion with constant acceleration?

Search the net; I'm sure you can find something...
 


There are many online resources available for practice problems on kinematics and 2D motion with constant acceleration. Some popular websites include Khan Academy, Physics Classroom, and Physics Classroom's "Minds on Physics" program. Additionally, many textbooks and study guides also include practice problems on this topic. It may also be helpful to ask your teacher or classmates for additional resources or to create your own practice problems using real-life scenarios.
 
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?
