Let's say I have:

41.115562000000, -74.047621000000


41.095640000000, -74.011084000000

Is there a formula to calcuate the distance between these two points?

It depends what degree of accuracy you are looking for. This article on geographical distance from wikipedia should be useful Since the points are so close together and not near a pole, you could safely use the spherical earth projected to a plane.
