I have some idea. I think the force of impact would be between 1 Newton and 10 Newton. That's saying the mass involved is between 0.001 g (typical mass of an ant) and 0.0001 g (because I don't know how much of the ant's actual mass is involved). The paper cites 10^6 g as roughly the top acceleration, which yields roughly between 1 N and 10 N of force. That's roughly between the weight of an apple and a 1 kg object. So, not much.
