Nicole's thrill obsession

I have always loved thrill rides since I was a kid. When we talked in class about the different velocities speed and everything else it brought up a red flag in my mind. The reason for this is my father who is also a thrill seeker is obsessed with the travel channel. On the travel channel they had different shows about thrill rides talking about the velocity and all the other forms of physics. I was able to find the videos for everyone describing it.
