AI Thread Summary
The escape speed from Earth for a spacecraft is calculated using the formula square root of 2GM/R, where G is the gravitational constant and R is the radius of Earth. A user calculated the escape speed to be 3.4 x 10 m/s but was informed that this value is incorrect. The radius of Earth used in the calculation was confirmed as 6.371 x 10^6 m, and the mass of Earth as 5.9742 x 10^24 kg. The discussion emphasizes the importance of using accurate values for G and the correct radius in calculations. Accurate calculations are crucial for determining the correct escape speed.

what is the escape speed from Earth for a 7500kg spacecraft ?
radius of Earth is 6.38*10m and mass is 5.98*10kg.

Homework Equations


square root of 2GM/R

3. The Attempt at a Solution . I found escape speed to be 3.4*10ms. Is this right?
 
Physics news on Phys.org
The radius of the Earth is 6.371x106 m.
The mass of the Earth is 5.9742x1024 Kg.

Your answer is not correct.
 
jimmy those were the given values in my test. And am still finding the same answers with yo values

Show the details of your calculation. (Including the exponents!)
 
What value are you using for G?

G is approximately 6.673x10-11 m3/kg*s2
 

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...
