How can I solve for v(t) when given F=Fo and v(t=0)=0?

AI Thread Summary
To solve for v(t) given F = Fo and v(t=0) = 0, start by using the equation v² = v₀² + (2/m)∫(x₀ to x) F(x) dx. Substitute F = Fo into the equation, which simplifies the integral. The challenge lies in deriving a time-dependent expression for v(t), as the initial attempts did not yield a variable t. It is suggested to establish a relationship between v, x, and x₀, and to utilize the fact that v = dx/dt. Proper formatting in LaTeX is also advised for clarity in equations.

See LaTeX[/B]

given that $$v^2 = v_o^2 + \frac{2}{m}\int\limits_{x_o}^x F(x) \ dx\ $$ find the speed v(t) and the position x(t) given that $$F = F_o$$ and $$v(t=0)=0$$. I tried plugging in $$F=F_o$$ for $$F(x)$$ in the above equation but solving this equation for v never yields any variable t. So my question is, how can I solve for v(t)?

There we go. Sorry if the spacing is a little off. I'm not good at LaTeX

First get a relation between ##v##, ##x##, and ##x_0##. Then note that ##v = \frac{dx}{dt}##.
 
mch the reason your equations are all spaced out is because you used the 'display math' delimiters which are double $ signs.

If you want to get in-line latex, which is what you need for some of your post, you can use double # instead.
 
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...
