How can I calculate the force of friction on a rocket launched at school?

AI Thread Summary
To calculate the force of friction on a rocket launched at school, the coefficient of friction formula (Friction = coefficient x Fn) is essential. The normal force (Fn) is known, but the friction force needs to be determined. The gravitational force (Fg) of 0.75 N represents the work done against gravity, but it does not directly provide the friction force. To find the friction force, one must consider the rocket's thrust and the effects of air resistance during its ascent. Understanding these dynamics will help in accurately calculating the force of friction.

I have to find the force of friction against a rocket that we launched at school. How would I do that?

I know coefficient = Friction/Fn

I only have Fn, how do I find the frinction?

I'm really lost :(

I have Fg = 0.75 N, so that would be the work done against gravity, right?

So how would I use that to find the force of friction (air resistence in this case, since the rocket is thrust upward)
 

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

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...

Thread 'A cylinder connected to a hanging mass'

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...
