#5. A rock is thrown straight down with an initial velocity of 14.5 m/s from a cliff. What is the
rock's displacement after 2.0 s? (Acceleration due to gravity is 9.80 m/s'.)

How would I get the answer

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 = 2.6 m below the tank bottom which is a = 6.7 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). report your answer in meters to two decimal places.
