Problem: A 47.0-kg stunt pilot who has been diving her airplane vertically pulls out of the dive by changing her course to a circle in a vertical plane.
Part A: If the plane's speed at the lowest point of the circle is 91.0 m/s, what is the minimum radius of the circle for the acceleration at this point not to exceed 4.00g?
I need help to find the minimum radius of the circle.
