Problem with drawing velocity vectors

Click For Summary
The discussion revolves around a user's difficulty in graphing velocity vectors for a baseball scenario involving a pitch and a hit. The user knows how to solve the problem but lacks the skills to accurately represent the velocities in Cartesian coordinates. Participants emphasize the importance of providing the full question to offer effective assistance. They suggest that sketching the velocities will clarify the situation and aid in solving the problem. Overall, the focus is on the need for clear communication and visualization in solving physics problems related to baseball.

Homework Statement



Hi all , I have a problem statement , I know how to solve it but I don't know how to graph velocities so I can use cartesian coordinate and thus have correct answers. Would you please help me ??

A pitcher throws a fastball, which crosses the plate with a speed of 95 mph and an angle of 5° relative to the horizontal. The batter hits it for a home run, launching it with 113 mph at an angle of 35° to the horizontal.

I have never watched a baseball match ! so can you help me ?

You haven't actually posted what the question asks you to do.
 
The question is not a problem ,the sketching will permit me to get it ! I have the needed formula

Does the diagram clear things up for you?

Without seeing the question, there's no way of knowing what you're supposed to do. If you've solved it, great, if not and you still need assistance - detail the question.
 

Thread 'Magnitude of buoyant force in fluids of different densities'

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?
