[QUOTE="Tom Lor, post: 4940660, member: 534917"] [h2]Homework Statement [/h2] I need to determine the magnitude of velocity and acceleration for an aircraft moving away from a fixed position (for example a radar station). I need to calculate the magnitude of velocity and acceleration for each time step. The following table of information is given [ATTACH=full]174666[/ATTACH][h2]Homework Equations[/h2] The magnitude of velocity is given as [tex]\sqrt{(\frac{dr}{dt})^2+(r\frac{d\theta}{dt})^2}[/tex] And acceleration [tex][\frac{d^2r}{dt^2}-r(\frac{d\theta}{dt})^2]^2+[r\frac{d^2\theta}{dt^2}+2\frac{dr}{dt}\frac{d\theta}{dt}]^2[/tex] [B]3.0 Attempt[/B] I am currently in the process of programming this into FORTRAN to get results but I am struggling to work out how to calculate. I am just hoping someone can point me in the right direction. I know I need to calculate the first and second derivatives but the fact I need to take an angle into account is confusing me somewhat. Also to add, how can I calculate a magnitude of velocity for time 0? [/QUOTE]
