A cutting tool under microprocessor control has several forces acting on it. One force is , a force in the negative y-direction whose magnitude depends on the position of the tool. The constant is ααalpha = 2.35 N/m³. Consider the displacement of the tool from the origin to the point x= 2.60 m , y= 2.60 m.
Calculate the work done on the tool by if this displacement is along the straight line y=x that connects these two points.

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.
