Question
I just need to see a diagram of what problem 3 would look like.
![3. Self-closing refrigerator door A door is constructed of a thin homogeneous slab of material of width w, with frictionless
hinges. If the door is opened through an initial angle ao </2, and it is released at rest, it closes itself in a time t.
Find a formula for the angle & that the line of hinges makes with the vertical, in terms of w, ao, t and g. Use your
formula to find 8 (in degrees) for the case w = 0.86m, ao = π/4, t = 1.5s, g = 9.81m/s². Is this consistent with your
experience with your refrigerator? (Recall that the moment of inertia of a rod of mass m and length & about one of
its ends is m02/3)
