Thank you very much, I think I have a basic understanding now! Very appreciate it!

I sincerely apologize for my lack of explanations. v is velocity and t is time. The rest are just constants. I want to integrate velocity vs. time to find the displacement equation

Homework Statement Integrate $$v = \sqrt{2g\frac{T-v \pi r^2t}{\pi R^2}}$$ where g,T,r,R are constants Homework Equations N/A The Attempt at a Solution I tried playing around with the variables, but I am not sure how to integrate this. Just give me a little bit of hint would do. Thanks!

Hey SteamKing, After following your suggestions, I was able to find the relationship between velocity and time: $$h = \frac{T-v \pi r^2t}{\pi R^2}$$ where T is the volume of the water, r is the radius of the hole, R is the radius of the container, and t is time $$v = \sqrt{2g\frac{T-v \pi...

Can you elaborate a little bit more? Thank you for your time :)

Both height and velocity change with time. Can I replace velocity with dh/dt?

Homework Statement Given the dimensions of a cylinder container with a hole, the dimensions of the hole, and the volume of water, calculate the time for water inside the container to completely leak out. Homework Equations Bernoulli equation: P + 1/2pv^2 + pgh = constant...

Woah! That is very impressive! By the looks of it, this is way beyond my capabilities haha. I will see what I can do, thanks for your help!

Unfortunately my knowledge of air resistance is very limited. The worst case would be assuming the birdie to be a sphere, and add uncertainties to the function. I believe my teachers would be fine with that. When you mention simulation, do you mean to create a computer simulation from scratch...

The hypothesis, or the calculation is done as a function: V = f(position, hit angle) where V is the initial velocity needed for the birdie to travel back so that it lands just at the back boundary line position is the position of the birdie hit angle is the angle at which the racket is going...

Thank you for your comments. I have added air resistance in my hypothesis now. Do you have any other suggestions?

Hello! The calculation is just solving kinematic equations for 2d projectile which excludes air resistance. I am comparing this equation with how birdie travels realistically by doing video analysis. Do you think this qualifies as a valid physics lab?

Sorry I didn't post this using the template :c, since this is not a Physics problem to solve. Hello everyone, I hope this is the right section to ask this.. I am in a program called International Baccalaureate and I need to write a 4000 word essay on Physics. My investigation is related to 2D...

Just to clarify: I only have very rudimentary knowledge of Physics, so please correct me if I am wrong. This thought came to my mind after I discovered some youtube videos and articles on the double slit experiment: AFAIK, if the information of which path the electron takes is obtained, there...

Ah, this is exactly what I m looking for, thank you so much!
