Calculate Flight Time of Artillery Shell

AI Thread Summary
To calculate the total flight time of an artillery shell fired at a 25.3-degree angle with an initial speed of 1890 m/s, one must apply projectile motion equations. The acceleration due to gravity is 9.8 m/s², and air resistance is neglected. The discussion highlights the importance of understanding the relationship between angle, initial speed, and gravity in determining flight time. Participants encourage sharing initial attempts to facilitate guidance. The conversation emphasizes starting with basic projectile motion principles to solve the problem effectively.

Hi sul6an! Welcome to PF! :smile:

(erm … what's "kicking ball" got to do with it?! :confused:)

Show us what you've tried so far, and then we'll know how to help you! :smile:
 
Nothing about kicking ball. I wrote it by mistake, sorry :?

I don't know how to start it :(

Surely this question is related to some subject you've been studying. That should give you a clue about where to start.

Do you know how to do it if it is 90º (vertically upward) instead of 25.3º? :smile:

Thread 'Minimum mass of a block'

Here we know that if block B is going to move up or just be at the verge of moving up ##Mg \sin \theta ## will act downwards and maximum static friction will act downwards ## \mu Mg \cos \theta ## Now what im confused by is how will we know " how quickly" block B reaches its maximum static friction value without any numbers, the suggested solution says that when block A is at its maximum extension, then block B will start to move up but with a certain set of values couldn't block A reach...

Thread 'Electric field due to charges between 2 parallel infinite planes'

TL;DR Summary: Find Electric field due to charges between 2 parallel infinite planes using Gauss law at any point Here's the diagram. We have a uniform p (rho) density of charges between 2 infinite planes in the cartesian coordinates system. I used a cube of thickness a that spans from z=-a/2 to z=a/2 as a Gaussian surface, each side of the cube has area A. I know that the field depends only on z since there is translational invariance in x and y directions because the planes are...
