5 A small ball is held at a height of 160 cm above a horizontal surface. The ball is released from rest and rebounds from the surface. After its first bounce on the surface the ball reaches a height of 122.5 cm .

1. Find the height reached by the ball after its second bounce on the surface. After \(n\) bounces the height reached by the ball is less than 10 cm .
2. Find the minimum possible value of \(n\).
3. State what would happen if the same ball is released from rest from a height of 160 cm above a different horizontal surface and
   (A) the coefficient of restitution between the ball and the new surface is 0 ,
   (B) the coefficient of restitution between the ball and the new surface is 1 .
