Help with simplifing and factoring an equation

mercredi 26 février 2014

Hey. I need help simplifying and factoring a differential equation in terms of v and p (velocity(xdot) and position(x) respectively). I need the final answer to be in this form:

a = ( )v + ( )p



Definitions:

m = mass

a = acceleration = xdotdot

v = velocity = xdot

p = position = x

b = constant

k = constant

c = constant



The equation is:

ma + (bv + kp) = ((cv)/(v^2 + p^2)^.5))



I simplified it below as:

a = ((mcv)/(v^2+p^2)^.5)-(bv-kp)
