A ball rolls horizontally off the top of a stairway with a speed of 1.52m/s. The steps are 1.52 cm high, and 20.3 cm wide, which step does the ball hit first.(adsbygoogle = window.adsbygoogle || []).push({});

I dont really know where to start, I kept trying to use the formulas..but I would always end up with two unknowns.

Can anyone point me in the right direction?
