    Launch Speed
AI Thread Summary
The discussion focuses on calculating the launch speed of a projectile that rises vertically to an altitude equal to one Earth radius. The formula proposed for this calculation is v_{orbit} = √(Gm/r), where G is the universal gravitational constant, m is the mass of the Earth, and r is the radius of the Earth. Participants clarify the components of the formula and its application to orbital mechanics. The conversation emphasizes understanding gravitational forces in relation to launch speed. Accurate calculations are essential for achieving desired altitudes in projectile motion.

Does anyone know the formula to find launch speed?

Launch in order to do accomplish what?
 
im sorry i think i got it.

its of a projectile that rises vertically above the Earth to an altitude equal to one Earth radius

is it:
square root of: (Universal gravitational constant of earth) x (mass of earth) all divided by Radius of earth?
 
<br /> v_{orbit}=\sqrt{\frac{Gm}{r}}<br />

Where G is universal gravitational constant, m is mass of orbiting body, and r is radius between bodies.
 

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...
