What is the accelerating force of a bullet in a 10cm gun barrel?

AI Thread Summary
To find the accelerating force of a 10g bullet in a 10cm gun barrel, first convert the mass to kilograms and the length to meters. Using the equation v^2 = vo^2 + 2a(x - xo), rearrange to solve for acceleration (a). Then, apply F = ma to calculate the force. The initial confusion stemmed from unit conversion, which is crucial for accurate results. Proper attention to units is essential in physics calculations.

Homework Statement

[/B]A 10g bullet accelerates from rest to 500m/s in a gun barrel of length 10cm. Find the accelerating force (assuming it is constant).

Homework Equations


F=ma, v^2=vo^2+2a(x-xo)?

The Attempt at a Solution


I tried using F=ma, but it does not equal the answer in the back of the book.

Have you converted the mass and length into kg and m? Then rearrange v2=vo2+2ax to find a. Then sub that into F=ma.

Oh jeez. Got it now, thank you. Gotta make sure I actually pay attention to units :(

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...
