Hi

i am using the latest version of space manager/chipmunk for my game. in my collision handler i am moving my ball to a different position. when the ball appears in the new location it still has the velocity and forces from its previous location. i want them to be zero when is put in the new location. i have tried this but it did not work.
```
ballsprite.shape->body->v.x =0;
        ballsprite.shape->body->v.y =0;
        ballsprite.position =  ccp(50, 100);
```
also tried [ballsprite resetforces]; just before setting its new location. it does not work either. any ideas?

You may have the integrationDt set, this basically calculates values for velocity when you call setPosition.

Regardless of that tho, you should be able to do this (I do in Trundle):
```
ballSprite.position = pt;

	ballSprite.shape->body->v = cpvzero;
	ballSprite.shape->body->w = 0;
```
