Click For Summary
To calculate the speed of a baseball hit straight up to a height of 295 ft, one must apply the principles of physics, specifically using kinematic equations. The problem requires showing work to receive assistance, as per forum rules. Members are advised against hijacking threads and should create separate posts for their own questions. The discussion emphasizes the importance of following the Homework Template for clarity and organization. Properly addressing these guidelines will facilitate better help from the community.

During the world series a ball is hit straight up from the batter's box and reaches a height of 295 ft. Neglecting air friction, what speed (mph) will the baseball attain if it is caught by the catcher at the same height it was hit?

You've got to show an attempt at solving your own problem in order to receive help.

Also, PF Rules require that you use the HW Template when posting HW problems.
 
I have this same problem and I've tried a few things but I can't get it either. Should I make another post or show my work here?

Yes. PF does not allow members to hijack other's threads.
 
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?
