CGPoint diff = ccpSub(new_location, oldTouchLocation);
CGPoint currentpos = [para6 position];
CGPoint destination = ccpAdd(currentpos, diff);
if (destination.x < 80 && destination.x > 20)
{
 Velocity = (20 + (80-destination.x))*1.8 ;
}

above is the sample example calculating velocity for my plunger

Velocity is defined as distance divided by time. So you would divide the pixels your sprite traveled within a given time period by the time elapsed.
