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:

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...

Thread 'Struggling to make relation between elastic force and height'

Hello guys this is what I tried so far. I used the UTS to calculate the force it needs when the rope tears. My idea was to make a relationship/ function that would give me the force depending on height. Yeah i couldnt find a way to solve it. I also thought about how I could use hooks law (how it was given to me in my script) with the thought of instead of having two part of a rope id have one singular rope from the middle to the top where I could find the difference in height. But the...
