When a small ball falls from the height h above the ground, the air resistance of the ball in the process of movement is k times of its gravity. When the ball collides with the ground, it can rebound at the same speed. Then the total distance of the ball from release to stop bouncing is______ ．

When a small ball falls from the height h above the ground, the air resistance of the ball in the process of movement is k times of its gravity. When the ball collides with the ground, it can rebound at the same speed. Then the total distance of the ball from release to stop bouncing is______ ．

In the whole process of the ball movement, only gravity and resistance do work. According to the kinetic energy theorem, there is: MGH FS = 0, where: F = KMG, the simultaneous solution is: S = HK, so the answer is: HK
