You are assigned the design of a closed, cylindrical, pressurized water tank for a future colony on mars, where the acceleration due to gravity is 3.71 meters per second per second. the pressure at the top surface of the water will be 110 kpa, and the depth of the water will be 14.3 m . the pressure of the air in the building outside the tank will be 94.0 kpa . the tank is stationary and held up from above, so that the bottom surface of the tank is in contact with the atmosphere in the building. find the net downward force on the tank's flat bottom, of area 2.15 m2 , exerted by the water and air inside the tank and the air outside the tank.

Aplayground merry-go-round has a radius of 4.6 m and a moment of inertia of 200 kg-m2 and turns with negligible friction about a vertical axle through its center. a child applies a 26.0 n force tangentially to the edge of the merry-go-round for 15.0 seconds. if the merry-go-round is initially at rest, how much work did the child do on the merry-go-round?
