An astronaut in outer space holds a 2.0 kg wrench in their hand. The astronaut and the wrench are initially at rest with respect to one another. The wrench is then thrown (ignoring any rotational effects) and an observing astronaut measures each body’s velocity following the throw. The wrench moves with a velocity of +8.0 m/s while the astronaut moves at -0.15 m/s. Calculate the mass of the astronaut.

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)
