During a severe storm in Palm Beach, Fla., on January 2, 1999, 33 inches of rain fell in a period of nine hours. Assuming that the raindrops hit the ground with a speed of 12 m/s, estimate the average upward force exerted by one square meter of ground to stop the falling raindrops during the storm. (Note: One cubic meter of water has a mass of 1000 kg.)
