How Does Increased Track Height Affect Object Acceleration?

Click For Summary
Increasing the height of the track affects the acceleration of an object due to gravitational potential energy conversion. A higher track height typically results in greater potential energy, which can lead to increased acceleration as the object descends. However, the specific impact on speed and acceleration depends on the track's design and frictional forces. Clarifying the setup is essential for accurate analysis. Understanding the distinction between speed and acceleration is crucial for solving the problem correctly.

The speed of the track was slower? is it correcT?thanks

You'll need to either show a figure, or give a better description, of the track and setup you are asking about. Otherwise we can't help you.

The question is about acceleration, not speed. Don't make random guesses.
 
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?
