They also had ridiculously tight seat belts that stapled us into our carts. The lap bar was tightly cinched to prevent us from flying out of the cart when we went downhill. The coaster had banked turns so that we could turn with ease without flipping over. instead of being a conventional bumpy wooden roller coaster, the Swiss manufacturer cut the wood pieces with a laser and then laminated them. Then he put the pieces together like a puzzle piece, rather than assembling wood timbers together. >> On the way up I didn't feel like my weight was any didn't feel like my weight was any different, but on the way down, I felt like my center of mass had moved higher and like I was flying out of seat. On the bottom of the hill, I felt so heavy, like I was cemented to my seat. >> On the way up: We were freaking out, mentally preparing ourselves for the drop to follow. >> On the way down: Again, I was flipping out due to the max speed and ridiculous angle of depression we were experiencing. >> At the bottom of the first hill: I was weary at this point, from clenching onto the lap bar to try and stay into my seat. >> One thrill factor was obviously the extremely steep angle, which gave the coaster the ability to achieve a max speed of 70mph (about 32 m/s).

 * 2) Calculate #g’s on the way down the hill and at the bottom of the hill: .997959 g's
 * 3) Were #g’s within safe limits? yes
 * 4) Was there correlation between #g’s and excitement level? Explain, providing evidence. Not really, I feel like we experienced more g's
 * 5) ** Thinking about Physics **
 * 6) Explain the behavior of the mass on the string. Did the FBD of the car correlate to that of the mass? Why or why not? The weight part of the FBD correlated to the mass on the string for the most part because weight always has to point straight down, but sometime it looked like it was hanging at an angle. To be honest we were going so quickly, it was hard to tell how the mass on the string was behaving.
 * 7) Did the #g’s correlate to the sensation of weight? Yes
 * 8) Discuss the graphs that you created and why they curve the way that they do. The distance vs time graph curves the way it does because the coaster goes way from the start, but then returns to the origin. The velocity and acceleration graphs curve because it have a constant speed while it's going up the hill, but then accelerates as it goes down the hill and around the curves and decelerates before returned to the base.

** PART A: At the park: **
>>> Circles = seats >> The seatbelt was the main source of safety. Many people used the pole supporting the seat to hold onto while riding the carousel. This ride was pretty slow and showed no sign of danger. Therefore, the seatbelt that fit around the waist sufficed. Many adults held their children while they were on the ride. >> >> **Excitement Level:** >> This ride was the most insane ride at six flags. I couldn’t’ help but scream while we were traveling at its max speed! It was tops blooby. >> >> **Thrill Factors:** >> This ride first of all traveled in a circle, which did it for me. Whenever I travel in circles, I feel as though I may be sick which makes the ride more exciting. Another thrill factor were the varying animal seats. This made the ride much more exciting because not only did it bring back childhood memories, but also I got to ride a unicorn. Lastly, the seats moved up and down as well as in a circle, which contributed to much excitement. >> >> **Apparent Weight:** >> There was no other change in feeling besides the fact that once the ride started, I felt as though I was being thrown out of my seat, away from the center of the ride. >>

 * 12) **Safety Features:**

** PART B) Back at School **
>> b. Centripetal Acceleration >> c. Apparent weight >> Was there correlation between #g’s and excitement level? >> No >>> 2. Well, no because the seat was in place while the string was moving freely. If the seat had enough slack, like the mass on the string, it would have behaved like the mass on the string. It was forced to stay still and showed no tendency of moving tangentially.

 * 2) Explain the behavior of the mass on the string.
 * 3) Did the FBD of the car correlate to that of the mass? Why or why not?
 * 4) 1. The mass on the string moved slightly to the left, away from the center, and stayed there until the ride stopped. This is because of inertia. The tendency for the mass to move in a straight line is what makes it move outward.
 * 1) Discuss the graphs that you created and why they curve the way that they do.
 * 2) The only graph that curves is the acceleration vs. thrill graph. It is because As the acceleration rises, so does the thrill during the ride.
