Figure 2 below shows water at a dam. The depth of the water at the dam is(adsbygoogle = window.adsbygoogle || []).push({});

20 meters. The area of the wall of the dam which is in contact with the water

is 500 m 2. The atmospheric pressure is 1 atmosphere and the mass per unit

volume density of the water is 1000 kg/m^3 Find the total force exerted on the wall which is in contact with the water.

so far ive found p=2.97e5

p=1.013e5+1000*9.8*20

p=F/A

F=2.97e5*500

F=1.485e8

i found avg pressure : (1.013e5+2.97e5)/2

=1.991e5

Im not sure what to do next please help
