Explanation / Answer
The time the drop travel 50 cm is: x=1/2 g t^2 => t = (2x/g) = 3.16 s When a drop hit the sink, there is another drop in the air andanother start to drop, which mean the interval between 2 drops isone half of the time that a drop travel 50 cm The interval between 2 drops is T = t/2 = 1.58s So in one min, the number of drop is 60/T ˜ 38(drops)
