 * 7) On the way up, you are pushed back and feel heavier. On the way down, you feel lighter. At the bottom, you feel normal because the only forces acting upon you are normal and weight which will equal each other.

 * 9) On the way up, you feel anxious for the upcoming drop. It is less exciting and slower. Going down is when the real excitement happens, you start to feel the adrenaline rush of the speed and drop. At the bottom of the hill, there is no thrill and is not noticeable.

 * 1) <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 90%;">Calculate #g’s on the way down the hill and at the bottom of the hill
 * 2) g=A/9.8
 * 3) g= 9.09/9.8
 * 4) # of gs= .93
 * 5) <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 90%;">Were #g’s within safe limits?
 * 6) Yes because there weren't more than 4 g's.
 * 7) <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 90%;">Was there correlation between #g’s and excitement level? Explain, providing evidence.
 * 8) Yes, It appears that as the number of g's increase, as does excitement level. We were asked to graph acceleration vs. time as well as thrill vs. acceleration, shown above. When there is no acceleration, thrill (or excitement level for that matter) is nonexistent. However when acceleration is greater, thrill is greater.


 * 1) <span style="font-family: 'Trebuchet MS',Helvetica,sans-serif; font-size: 90%;">Thinking about Physics
 * 2) 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?
 * 3) Yes the mass of the string correlated to our FBD of the car. When the string learned forward being "tugged" up the coaster, so did the car. When the string evened out at the top of a hill, as did the FBD.
 * 4) Did the #g’s correlate to the sensation of weight?
 * 5) Yes because as the number of g's increase, so does apparent weight.
 * 6) Discuss the graphs that you created and why they curve the way that they do.
 * 7) D vs T
 * 8) The graph has a slow incline because that is how the ride starts. The graph then has a steeper sloped and as the cart goes down the hill due to the speed and acceleration increasing that means there is more distance being covered in a shorter amount of time.
 * 9) V vs T
 * 10) Velocity is constant on the way up to the first drop and then velocity increases.
 * 11) A vs T
 * 12) There is no acceleration at first because there is a constant velocity on the way to the first drop. As the car goes down the hill, the velocity increases and changes on the hills and valleys therefore the acceleration increases.
 * 13) Thrill vs Acceleration
 * 14) There is no thrill because there is no acceleration but once the cart goes over the first hill down the drop the thrill amount increases for the rider.
