A woman is riding a Jet Ski at a speed of 28 m/s and notices a seawall straight ahead. The farthest she can lean the craft in order to make a turn is 20°. This situation is like that of a car on a curve that is banked at an angle of 20°. If she tries to make the turn without slowing down, what is the minimum distance from the seawall that she can begin making her turn and still avoid a crash?
What I did:
v = 28 m/s
r = ?
g = 9.81 m/s^2
Theta = 20 degrees
r = (28 m/s)^2 /(tan(20) x (9.81 m/s^2))
r is estimated to be about 219.574 m
Am I correct in this case?

Looks reasonable to me.
