Well, I have also computed the components of the acceleration, a_x and a_y, so I guess I could do it component-wise

It is a pendulum where we think of the rope as a spring

I'm somewhat familiar with it. I was thinking that since we know r(0), v(0) and a(t), I could simply compute r(t) = r(0) + v(0)*t + ∫∫a(t)dtdt, but I do not know how to integrate a(t) when it depends on r(t)

I have computed that the acceleration in my problem is a(t) = -gj - k/m(|r(t)| - L_0) * r(t)/|r(t)| Where a(t) is the acceleration vector, g is the gravitational acceleration, j is the unit vector in y-direction, k is the spring constant, m is the mass, r(t) is the position vector, |r(t)| is...
