Also regarding knocking the Enterprise out of warp in that clip, it wouldn't happen. It would simply stop the ship where it was and it would be the other ship that would continue on at near infinite velocity.
Although the Abramsverse already established earlier that the plot drives of the ships don't use warp but instead transport the ship near instantaneously, which also you can do individually thanks to Scotty's infinite transport formula, also despite this the best way to get over to another ship is to jump out of it in space suits and try to fly yourself over to it.
Really, the way the "warp" works in both films shows why everyone thought he'd be ideal for Star Wars, it operates as hyperspace does. The weapons/shields operates as they do in Star Wars. Even JJ can't grapple with transporting and whether or not the momentum stays even though it never really has. To the point where Spock KNEELS DOWN so that when he comes out of transport to chase Khan to punch him in the face a hundred times he doesn't fall immediately. (Something he didn't do when beaming down onto a planet that was imploding mind you. So much for the tolerant le- Vulcan logic.)
Beyond actually goes out of its way to mention how the transporters Jaylah provides for the crew don't operate as normal and are more dangerous. Even though Kirk and Jaylah keeping their momentum and spatial location, thus falling, is how the normal transporters have operated to date. (Pegg must have forgot!)
