Alpha Cam: Runaway Star

So I was reading this site APOD, to quote for the page; “Astronomers have long thought that Alpha Cam was flung out of a nearby cluster of young hot stars due to gravitational interactions with other cluster members or perhaps by the supernova explosion of a massive companion star.” Now I have no problem with celestial mechanics which would see a star flung out of its birth place. But think of the kind of force required to push a star via an exploding star (supernova) and hurl it through space at 60 kilometres per second. This is a star about 25-30 times as massive as the Sun. I find this sort of force stunning. Though the universe hold many for powerful phenomena this sort of thing never cease to amaze me.
