Roger Barnett · Answer 1

The solution for this problem is:

If they feel 50% of their weight that means that the centripetal force is also 50% of their weight 1g - 0.5g = 0.5g

Then 0.5 * 9.8m/s² * 18m = 88.2 would be v²

Then get the square root, the answer would be:

and v = 9.391 m/s is the answer.
