AP Physics Free-Response Practice Question

AI Thread Summary
The discussion focuses on solving a physics problem involving a cylindrical tank filled with water and a hole at the bottom. Participants are tasked with calculating the speed of water flowing out, the volume rate of flow, the total volume collected in a tray over two minutes, and the time for a droplet to fall a specific distance. One user mentions using Bernoulli's equation but expresses confusion about the calculations and the given height. Others encourage clarity in calculations and adherence to forum guidelines for effective assistance. The thread emphasizes the importance of detailed problem-solving steps in physics discussions.

A cylindrical tank containing water of density 1000 kg/m^3 is filled to a height of 0.70 m and placed on a stand. A hole of radius 0.0010 m in the bottom of the tank is opened. Water then flows through the hole and through an opening in the stand and is collected in a tray 0.30 m below the hole. At the same time, water is added to the tank at an appropriate rate so that the water level in the tank remains constant.

(a) Calculate the speed at which the water flows out from the hole

(b) Calculate the volume rate at which water flows out from the hole

(c) Calculate the volume of water collected in the tray in t = 2 minutes

(d) Calculate the time it takes for a given droplet of water to fall 0.25 m from the hole

Well...I started with Bernoulli's equation and calculated the height to find out how far it sinks? And then I calculated the displacement? I don't know...

Do not crosspost. And please read the forum guidelines.

Which part are you referring to? What height did you calculate? You are already given the height. Please show your calculations explicitly for each part. It's very hard for us to decipher what you've done.

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
