First floor:
s = v0 * t + ½ * a * t2
s = 0 * 0. 70 + ½ * 9. 8 * 0. 702
s = (9. 8 * 0. 49)/2
s = 2. 401 to 2. 40 meters
Second floor:
s = v0 * t + ½ * a * t2
s = 0 * 1 + ½ * 9. 8 * 1
s = (9. 8 * 1)/2
s = 4. 9 to 4. 90 meters
Third floor:
s = v0 * t + ½ * a * t2
s = 0 * 1. 25 + ½ * 9. 8 * 1. 252
s = (9. 8 * 1. 5625)/2
s = 7. 65625 to 7. 66 meters
Fourth floor:
s = v0 * t + ½ * a * t2
s = 0 * 1. 49 + ½ * 9. 8 * 1. 492
s = (9. 8 * 2. 2201)/2
s = 10. 87849 to 10. 88 meters
Fifth floor:
s = v0 * t + ½ * a * t2
s = 0 * 1. 76 + ½ * 9. 8 * 1. 762
s = (9. 8 * 3. 0976)/2
s = 15. 17824 to 15. 18 meters
