Starting from the front door of your ranch house, you walk 60.0 m due east to your windmill, and then you turn around and slowly walk 35.0 m west to a bench where you sit and watch the sunrise. it takes you 30.0 s to walk from your house to the windmill and then 48.0 s to walk from the windmill to the bench.

Water is siphoned from a large tank and discharges into the atmosphere through a 50-mm diameter tube. the end of the tube is b = 2.1 m below the tank bottom which is a = 7.4 m deep, and viscous effects are negligible. determine the maximum height h over which the water can be siphoned without cavitation occurring. atmospheric pressure is 101.4 kpa, and the water vapor pressure is 1.79 kpa (absolute)
