As per the given data
Rise of the ball for first bounce = 48 × 2/3 = 32 m
Rise of the ball for second bounce = 32 × 2/3 = 64/3 m
Rise of the ball for third bounce = 64/3 × 2/3 = 128/9 m
Rise of the ball for fourth bounce = 128/9 × 2/3 = 9.48 m
Rise of the ball for first bounce = 48 × 2/3 = 32 m
Rise of the ball for second bounce = 32 × 2/3 = 64/3 m
Rise of the ball for third bounce = 64/3 × 2/3 = 128/9 m
Rise of the ball for fourth bounce = 128/9 × 2/3 = 9.48 m
