Roller Coasters When a roller coaster descends at high speeds, the force exerted on a rider’s body by the roller coaster becomes less than that of gravity, producing a sensation of weightlessness. Then when the roller coaster hits the bottom and either shoots up or turns sharply, a g-force is exerted on the rider’s body for a fraction of a second. This g-force can be stronger than the one felt by astronauts during a space shuttle launch.
For Exercises 63-66, refer to the bar graphs, which display the top speeds and maximum drops
for some of the most popular roller coaster rides.
How much less is the maximum drop of Superman: Escape from Krypton than that of Top Thrill Dragster?
