3. A lasso is whirled in a loop that approximates a circle of radius 2.6 m. If it takes 4
seconds for the lasso to make one revolution, what is its angular velocity, its
tangential velocity and its period? (1.6 rad/s; 4.1 m/s; 4 s)

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)
