A truck is travelling at a constant velocity of 22 m/s [North]. The driver sees a traffic light turn from red to green soon enough, so he does not alter his speed. Meanwhile, a woman in a sports car stopped at the red light. At the moment the light turns green and the truck passes her, she begins to accelerate at 4.8 m/s 2?

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)
