Unfortunately i did not have a camera or my phone with me at the time, but hopefully my drawing is good enough. This weekend i went to zippy's to eat breakfast with my family and i noticed a big window decoration-thing. This thing was a picture of santa clause being pulled in his sled by his reindeer. The peculiar thing i noticed about the picture was that the reindeer were not hooked up to the sled, rather, santa was holding the reindeers' reins with one hand and waving with the other. My first thought was how strong santa must be to be able to hold onto the reindeer like that with one hand. I mean, the reindeer must be exerting a huge force on the reins to be able to pull santa and a sled full of toys. Due to Newton's second law of motion, this same force must be matched by santa's one hand in order for the picture to be plausible. I guess if santa can fly around the world in one night, he can probably exert large amounts of force with one hand.
