Question:
The “g-force” experienced by people sitting on a roller coasteris equal to the normal force of the seat pushing ‘up’ on themdivided by their mass. Suppose a roller coast is to have a verticalloop of radius R.
a. Assuming the loop is circular, calculate the minimum startingheight for a car to make it over the top of the loop with theriders being weightless (i.e. with g-force = 0).
b. Using this starting height, determine the “g-force”experienced by people at the bottom of the loop.
c. People will pass out when g-forces exceed 5 or 6 g for anylength of time. How could you tweak the design of your verticalloop to ensure the physical safety of the riders on yourrollercoaster, by keeping the g-force at the bottom below 4 “g’s”?
