Instead of the usual ball release from rest, this question states that the ball has an initial velocity greater than terminal velocity in the air.
There are a few scenarios which are possible.
object moving in vacuum at high speed entering air (e.g. meteor entering Earth's atmosphere)
object is thrown down from a high altitude at high speed
parachute is opened and the speed decreases till terminal velocity
stone falling with high speed in air hits the water and speed decreases
etc
View the video for the explanation.
