A baby bird leaves its nest and flies 5 miles north then 10 miles south. It took 1 hour total. a) What distance did it fly?
b) What is it's displacement (relative to the nest)
c) What is it's average speed for the trip?
d) what is it's average velocity for the trip?

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.
