AP10005 Physics I Tutorial 7 (Chapters 17‚ 18) 1. (17P11) A flower pot is knocked off a window ledge from a height d = 20.0 m above the sidewalk as shown in the figure below. It falls toward an unsuspecting man of height h =1.75 m who is standing below. Assume the man requires a time interval of Δt = 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? 2. (17P15)
