I am working on an AP physics question that I am supposed to solve by using an integrated force(not an average) and I am a bit stumped. Please help!(adsbygoogle = window.adsbygoogle || []).push({});

An 8 kg turkey is placed 1 m(from their centers of mass) from an 8 kg ham on a friction less table. How much time passes before the turkey and ham touch?

(A picture that is above the question shows both the turkey and ham to be .2m wide, so it is only a distance of .8 m before their edges touch)

I have started by finding the integral of F=GMm/r^2 dr (from 0 to .4) by plugging in the gravitational constant and both 8 kg masses for M and m. I found the indefinite integral to be (4.27*10^-9)/r and the definite integral to be -1.07*10^-8 N Is this the work that I've found, and if so(or if not) where do I go next?
