    (10-x)^2 + (3)^2 = x^2 100-x^2 + 9 =x^2 109 = 2x^2 Therefore, x^2 = 109รท2 = 54.4 Therefore, x= root 54.4 Which equals approximately 7.37 feet

    The acceleration should be separated not averaged. The correct answer for part be is 2548N and this is how: Fnet= F2+F1 in order to find F1 and F2, use F=ma. The acceleration for F1 is gravity as it's the part where the diver hits the water. Mass is 65kg.
