A trough whose cross section is a semicircle of radius r = 8 m is filled with water to a depth of h = 4 m. What is the force due to water pressure on one end of the trough? (Hint: The mass density of water is 1000 kg/m , g = 9.8 m/s2.) (Use decimal notation. Give your answer to the nearest whole number. Express your answer in kilonewtons (recall that 1 kN = 1000 N.)) 596 F ~ kN Incorrect
