A student at a window on the second floor of a dorm sees his moth professor walking on the sidewalk beside the builiding. he drops a water ballon from 18.0 meters above the ground when the professor is 1.00 meters from the point directly beneath the window. if the professor is 170 cm tall and walks at a rate of .450 m/s, does the balloon hit her? if not, how close does it come?
