Curling is a sport in which players slide stones on a sheet of ice toward a target area which is segmented into four concentric circles. A curling player released his stone at a rate of 3m/s. When the stone was released, the distance between the stone and the center of the target area was 30m. Assume the stone was moving towards the center of the target area without rotation, and the coefficient of kinetic friction of the ice is 0.02. The mass of the stone is 20kg. When the stone stopped, what's the distance between the stone and the center of the target area?
