Asolid wood door = 1 3 ) 2 ) 1.00 m wide and 2.00 m high is hinged along one side and has a total mass of 44.0 kg. initially open and at rest, the door is struck at its center by a handful of sticky mud with mass 0.700 kg , traveling perpendicular to the door at 14.0 m/s just before impact. find the final angular speed of the door in (rad/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 = 2.6 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.

The first law of thermodynamics states that heat added to a system is neither created nor destroyed but is as it changes into other forms of energy.
