A ball rolls off a stairway with a horizontal velocity of 5.0 ft/sec. The steps are 8.0 in high and 8.0 in wide. Which step will the ball land on first? I was thinking we could find the time it takes for the ball to go 8in in the X direction(using our motion equations), then plug that in for the Y location and see where we would be. After that I am not sure, I would know if we had the height of the stairway.
