AI Thread Summary
Superman throws an asteroid at 800 m/s, which is significantly more massive than himself. The problem involves calculating Superman's recoil velocity using the principle of conservation of momentum. When the asteroid is hurled, Superman must experience a backward motion to conserve the total momentum of the system. The recoil velocity can be determined by applying the conservation of momentum formula. Understanding recoil velocity is essential in solving this physics problem effectively.

Homework Statement


Comic-strip hero Superman meets an asteroid in outer space and hurls it at 800 m/s, as fast as a bullet. The asteroid is a thousand times more massive than Superman. In the strip, Superman is seen at rest after the throw. Taking physics into account, what would be his recoil velocity?

What is a recoil velocity and how do I solve this problem? I would highly appreciate your contribution.

recoil is what guns (and cannon) used to do …

the gun kicks backward into your shoulder, so as to conserve momentum when the bullet flies forward …

in this case, the question is simply asking for the (ordinary) velocity of Superman (and you should use conservation of momentum) :wink:
 
hello leehana10! welcome to Physics forums!

from conservation of momentum, the velocity that superman will have is the recoil velocity of superman.
 

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'

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...
