1. The problem statement, all variables and given/known data Fx=-dV/dt where V=-(Voa2)/(a2+x2) 2. Relevant equations How to solve this equation? 3. The attempt at a solution Fx=ma =md2x/dt = -dV/dt =-d-(Voa2)/(a2+x2)/dt. If I differentiate -(Voa2)/(a2+x2) I get more complicated results which Im unable to solve. PLEASE HELP ME cause I studied how to solve second order differential equations but this look dufferent.
