Astronauts in space "weigh" themselves by oscillating on a spring. suppose the position of an oscillating 70 kg astronaut is given by x=(0.34m)sin((πrad/s)⋅t), where t is in s. what force does the spring exert on the astronaut at t = 1.0s. note that the angle of the sine function is in radians.

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)
