Sledding

I always enjoyed sledding, and now I can see how physics applies to the activity. For example, you can calculate the velocity of both the person and the sled after they are "one object" if you know the momentum of both before the person jumps onto the sled. If I weigh 63 kg, and I jump onto a stationary sled that weighs 5 kg at a velocity of 8 m/s, then I can add up the masses to get 68 kg times the velocity of both me and the sled. I can set 504 (kg x m/s) equal to (68kg)(v), because the momentum is the same before and after, and then divide 504 by 68, to find a velocity of 7.4 m/s for both objects.
