A flower pot is knocked off a window ledge from a height d = 20.8 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h = 1.79 m who is standing below. Assume the man requires a time interval of At = 0.300 s to respond to the warning. How close to the sidewalk can the flower pot fall before it is too late for a warning shouted from the balcony to reach the man in time? m
