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 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
