Just to clarify: Claws CAN generate enough force to stop a cannonball. He just won't feel well after that.
The world record for sprinting speed is 28 MPH, while the tip of a sword can acellerate to speeds of 75 MPH or greater, since the blade actualy acts as a lever, increasing speed in exchange for force advatage closer to its tip. In other words, the tip of a sword whacks harder, but it is harder to keep the sword in position if somebody else strikes the tip, which is actualy often used in swordfighting to bat away an opponent's atacks.
So realisticaly, Claws could strike with a speed just under the sound barrier, which is roughly 700 MPH. However, that may need clarification, as tier 3 characters probably aren't allowed to be that strong, and you'll get a major nerf to swing speed or something. Still, i think my point about Claws being strong enough will stand true.
