Practice problem
Gravity (Weight)
A pumpkin is dropped from the top of a building 20 meters tall. The bottom of the pumpkin is circular with a diameter of 10 cm. An ant crawling on the ground at a rate of 2 cm/sec happens to pass directly under the center of the pumpkin at the moment it is released.
At a minimum, how much faster does the ant need to crawl in order to escape the falling pumpkin?
