Problem

Water drops fall at regular intervals from a tap 5 m5\ \text{m} above the ground. The third drop is leaving the tap at the instant the first drop touches the ground. How far above the ground is the second drop at that instant? Take g=10 m s−2g=10\ \text{m s}^{-2}. (1) 1.25 m1.25\ \text{m} (2) 2.50 m2.50\ \text{m} (3) 3.75 m3.75\ \text{m} (4) 4.00 m4.00\ \text{m}
