A ball rolls off the top of a stairway horizontally with a velocity of 4.5 m/s. Each step is 0.2 m high and 0.3 m wide. If g is 10 m/s^2, and the ball strikes the edge of nth step, then n is equal to A ball rolls off the top of a stairway horizontally with a velocity of 4.5 m/s. Each step is 0.2 m high and 0.3 m wide.
