The figure to the right shows the shape and dimension of a small dam. Assuming the water level is at the top of the dam and that the shape of the dam is a semicircle, find the total force on the face of the dam. Use
1000k(g)/(m^(3))
for the density of water and
9.8(m)/(s^(2))
for the acceleration due to gravity. semicircle is the bottom of the tank. Choose the correct answer below. A.
w(y)=2\sqrt(y^(2)-49)
B.
w(y)=2(y^(2)-49)
C.
w(y)=2(49-y^(2))
D.
w(y)=2\sqrt(49-y^(2))
choice. (Type exact answers.) A.
\int 1dy
B.

Also need total force =??
