The motion of a solid object can be analyzed by thinking of the mass as concentrated at a single point, the center of mass. If the object has density ρ(x,y,z)ρ(x,y,z) at the point (x,y,z)(x,y,z) and occupies a region WW, then the coordinates (x¯¯¯,y¯¯¯,z¯¯¯)(x¯,y¯,z¯) of the center of mass are given by
x¯¯¯=1m∫WxρdVy¯¯¯=1m∫WyρdVz¯¯¯=1m∫WzρdV,x¯=1m∫WxρdVy¯=1m∫WyρdVz¯=1m∫WzρdV,
where m=∫WρdVm=∫WρdV is the total mass of the body.
Consider a solid is bounded below by the square z=0z=0, 0≤x≤40≤x≤4, 0≤y≤10≤y≤1 and above by the surface z=x+y+3z=x+y+3. Let the density of the solid be 1 g/cm33, with x,y,zx,y,z measured in cm. Find each of the following:
