Quick Help: Identical Guns Fired on Earth & Moon | 3 Possible Answers

AI Thread Summary
When identical guns fire bullets horizontally from the same height on Earth and the Moon, the bullet on the Moon experiences less gravitational pull, resulting in a longer flight time. Consequently, the horizontal distance traveled by the bullet on the Moon is greater than that on Earth. The bullet on Earth, however, falls faster due to stronger gravity, leading to a shorter flight time. The velocities of the bullets at impact are not the same, as the bullet on the Moon retains more energy due to its longer flight time. Therefore, statements a) and b) are true, while statement c) is false.

Homework Statement



Identical guns fire identical bullets horizontally at the same speed from the same height above level planes, one on the Earth and one on the Moon. Which of the following three statements is/are true?

a) The flight time is less for the bullet on the Earth.
b) The horizontal distance traveled by the bullet is greater for the Moon.
c) The velocity of the bullets at impact are the same.

I need to pick all the ones that apply. I think b)would be one, but I don't know what else, if any.
 
Physics news on Phys.org
a) Which falls faster?
b) Depends on ans of (a).
c) Which one gains more energy?
 
The one on the moon stays in the air longer because of the much lower gravity, so does that mean both a) and b) are true?
 
Yes.
 
Ok but c) wouldn't be true right?
 
As I asked, where will it gain more energy, if at all?
 

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...
