AI Generated Solution

To solve the problem of determining which step the ball will hit first, we can break it down into a series of steps: ### Step 1: Understand the problem The ball rolls off a stairway with a horizontal velocity of 150 cm/s. The height and width of each step are both 20 cm. We need to find out which step the ball will hit first. ### Step 2: Set up the equations Let: - \( n \) = number of the step the ball hits ...
