 a. The coaster reaches a height of 195 feet and drops unsuspecting riders 170 feet at a speed of 111.7 feet/second. b. The coaster races at a speed of 76.2 mph. c. The speeds most likely differ because the speed we calculated was the fatest, when it drops. The speed on the website they may have calculated at one of its slower points like when it was taking a turn or going uphill.

 The coaster drops 114 feet at a speed of 91.2 feet/second. The coaster reaces at a speed of 62.2 mph. A characteristic in the equation that would effect the speed would have to be the height of the coaster when it drops. The formula v=Square root of 2gh The v stands for the speed of the coaster, the g stands for the acceleration due to gravity, and the h stands for the height of the coaster in feet at the point it drops.
