Physics of Skiing

Last night while skiing, I started to think about the physics behind it all. Since my surgery last year, I am very cautious about the velocity I go down the hill. Whenever someone comes close to me or speeding past me, it is very nerve wracking. Because I am smaller than most other skiers, if we collided, I would most likely experience the bigger change in velocity and impulse (J).

During my accident last year, I was barely moving about to stop, going a velocity of probably .5 m/s when I was hit by a skier with a velocity of who knows what, but it was a lot more than mine. Using the table that Mr. Fullerton taught us, we could set it up to see our velocity as we hit each other and "became one." Click the link below to see the calculations:
