Range of a cannon using trigonometry?

AI Thread Summary
The discussion revolves around solving a trigonometric equation related to the range of a cannon. The user initially struggles with rearranging the equation to isolate x but later realizes the solution is straightforward. The equation involves terms such as tan, g (acceleration due to gravity), and initial velocity (Vo). The user expresses relief after figuring out the rearrangement process. Ultimately, the conversation highlights the common challenges faced in physics problems involving trigonometry.

Homework Statement


I am just stuck on a step in my problem , I have found the solution but have been attempting rearrange the equation but I just don't get it. Its probably a simple step

Homework Equations



0=x[(tanα-tanθ)-(gx/2Vo^2Cos^2(α)]

then this forms into this

x=(tanα-tanθ/g)(2Vo^2Cos^2(α))

The Attempt at a Solution


How do you get the X to the other side. There is a parentheses next to the x so you can divide anything out?

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...
