cpShape *shapeDisk = [self.spaceManager addCircleAt:cpvzero mass:10 radius:25 ];
shapeDisk->collision_type = kDiskCollisionType;
shapeDisk->u = 25;
shapeDisk->e = 0.9;

cpCCSprite* disk = [cpCCSprite spriteWithFile:@"disk.png"];
disk.shape = shapeDisk;
disk.position = SLING_POSITION;

Are you asking about when you create it:
```
cpShape *shapeDisk = [self.spaceManager addCircleAt:cpvzero mass:3000 radius:25 ];
```
or when you're in some code later and want to change it:
```
cpBodySetMass(shapeDisk->body, 3000);
```
