Can someone please explain it to me ASAP???!!?!! Physical application

The gure to the right shows the shape and dimension of a small dam. Assuming the water level is at the r0 4 m -| top of the darn and that the shape of the dam is an isosceles triangle. nd the total force on the face of the T dam. 24111 J Find the width function w(y) for each value of y on the face of the darn. Place the origin at the center of the base of the dam, with the y-axis going in the vertical direction and the x-axis going in the horizontal direction. Choose the correct answer below. A. W(y)=6y B. W(y)=12y 1 v 1 C. w(y)-12y ~ 0- WOO-BY Set up the integral that should be used to find the total force on the face of the dam. Use increasing limits of integration.
