A tap drips at a rate of 1 drop per second. What is the distance between the 1st and 2nd drops when the 1st drop has been falling for 3 seconds? (g=10 m/s^2)
A25 m
B45 m
C20 m
D5 m
✓ Correct Answer: A — 25 m
1st drop falls for 3s (s1 = 0.5*10*9=45m). 2nd drop falls for 2s (s2 = 0.5*10*4=20m). Difference = 25m.
