1. Quick Question:
The Top Thrill Dragster Coaster is the 2nd
highest in the world. The ride goes 853 m in
17 seconds. Calculate its average speed.
After reaching the highest point, the speed
changes from 0 to 160 km/h in 3.8 seconds.
Calculate its acceleration.
One train weighs 13,607 kg. At its fastest speed (160 km/hr), what is the net force on the train?
Sometimes, the force applied by the hydraulic launch system is not enough to power the train 420 feet in the air at a 90 degree angle and it rolls back to the launch position. What factors might cause this to occur?

2. Where must the speed of the roller coaster be the greatest?
0:13 in the video
0:15 in the video
0:21 in the video
0:25 in the video

3. Where must the acceleration of the roller coaster be the greatest?
Between 0:11 and 0:15 in the video
Between 0:15 and 0:20 in the video
At 0:21
Between 0:22 and 0:26 in the video

4. How would you compare the acceleration while going up with the acceleration while coming down?
They are equal.
The acceleration going up is greater.
The acceleration going down is greater.
They have the opposite sign.
