Homework Statement
Large limestone caverns have been formed by dripping water. If water droplets of 0.0305 mL fall from a height of 5.17 m at a rate of 14 droplets per minute, what is the average force exerted on the limestone floor by the droplets of water during a 1.00-min period? (Assume the water does not accumulate on the floor)

The Attempt at a Solution
I think I've tried everything for this problem. http://answers.yahoo.com/question/index?qid=20100411190028AANzFA6 - I tried following this but it doesn't give me the right answer. So I calculate momentum but then how do I find impulse if I don't know the length of time for the impact? I'm really confused.
