Your brother is opening a skateboard shop. He has created a sign for his shop made from 3/8" plywood in the shape shown in the figure. The areal density (6= M/A) is 1.12 1b/ft), or 5.47 kg/m' = o. The curve on 1.00 m the top of the sign is described by the function y = a(x - b), where a = - and X 9 m 3/8 in. b =3 m. Calculate the moment of inertia of 3.00 m the sign about the y axis
