Play animation after falling?

Hey so i want it so, After the player has Fell and landed, so it plays the animation. What code would i use for this?

If it helped im Using First Person Character Controller. I appreciate any help. Thankyou

Maybe use IsGrounded as a variable and then if IsGrounded is false for a certain amount of seconds, for example, 5 seconds, then when it IsGrounded is true make it play the animation?
