Finding Delta V of a Rocket: An Overview

AI Thread Summary
Delta V (∆v) represents the increase in speed during a rocket's main burn phase. The discussion highlights confusion regarding the inclusion of a 1 km/s value in the delta V calculation, which is suggested to be the speed just before the rocket's main engine ignites. This value is notably higher than the Earth's rotation speed, raising questions about its origin. Understanding these parameters is crucial for accurately calculating a rocket's delta V for successful launches. Clarifying these elements is essential for completing the assignment effectively.

I am doing an assignment about launching a rocket and at the moment I am looking for the delta V of the rocket. I have done a few researches and i found a method of finding the energy of the rocket and find the delta vee of it , but then i found this article and I am not sure if it is delta vee or not, and i don't get why there is a 1km/s in the equation

hi marco12345a! welcome to pf! :smile:

∆v is the increase in speed while the main rocket burns

1 km/s must be the speed just before the main rocket starts to burn

(but i don't know where that comes from … it's over twice the Earth's rotation speed :confused:)
 

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...
