To solve the problem of how deep the ball sinks in water after falling from a height of 9 cm, we will follow these steps: ### Step 1: Calculate the velocity of the ball just before it enters the water. The ball falls from a height \( h = 9 \, \text{cm} = 0.09 \, \text{m} \). We can use the equation of motion to find the velocity just before it enters the water: \[ v = \sqrt{2gh} \] ...
