A 50.0 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.
a) If the plane's speed at the lowest point of the circle is 90.0 , what should the minimum radius of the circle be in order for the acceleration at this point not to exceed 4.00 ?
b) What is the apparent weight of the pilot at the lowest point of the pullout?
