Dear All
I am trying to solve a differential equation,it is showing running and running for more than 3 hrs can anybody help me
the differential equation is

DSolve[x''[t] - (((x[t]^3) - (3*r*x[t]^2) + (2*x[t]*r^2)) - ((r^2)*ArcCos[1 - x[t]/r]*Sqrt[(2*r*x[t] - x[t]^2)]) + (Sqrt[(2*r*x[t] - x[t]^2)])) ==
0, x, t]
