Can someone please explain it to me ASAP?!!!?!?! This is a Physical Application.

A large tank has a plastic window on one wall that is designed to withstand a force of 90000 N. The square window is 2 m on a side, and its lower edge is 1 m from the bottom of the tank. Use 1000 kg f m3 for the density of water and 9.8 m I s2 for the acceleration due to gravity. 3. If the tank is lled to a depth of 4 m, will the window withstand the resulting force? b. What is the maximum depth to which the tank can be lled without the window failing? 21. Draw a yaxis on the face of the window in the vertical direction and choose a convenient origin. In this case, choose the point on the bottom of the tank that corresponds to the left Ay side of the window as the origin (0,0). as shown to the right. Find the width function w(y) for each value of y on the face of the window. 4 a 3 w(y)= 2 9' (Type an integer or a decimal.) 2 ' E ' 1 .
