Find the mass of the following thin bar. A 5-m bar with a density (in g/m) of p(x) = 250e for 0x5 For a thin bar or wire represented by the interval axb with a density function p (with units of mass per length), what is the mass of the object? d OA. m = P(x) OB. m= b dx Sp(x)dx a d OC. mxp(x) C dx b OD. m= xp(x)dx =Sxp(x)dx
