[QUOTE="yugeci, post: 4848452, member: 396292"] [h2]Homework Statement [/h2] [ATTACH=full]172538[/ATTACH] How does one get the r" equation from r'? [h2]Homework Equations[/h2] r = distance v = r' = ds/dt a = r'' = dv/dt chain rule, dy/dt = dy/dx * dx/dt [h2]The Attempt at a Solution[/h2] I can easily get to r' from r using the chain rule but how do you derive r" from r'? How do you apply the chain rule when there are 3 variables (sec theta, tan theta and theta dot)? Help would be appreciated. [/QUOTE]
