Problem 1.46 [Difficulty: 2] Given: Standard British golf ball: mg t o Dm m t o 459 0 3 20 1 411 0 3 20 1 .. ( ) ( ) Find: Density and specific gravity; Estimate of uncertainties in calculated values. Solution: Density is mass per unit volume, so ρ π ππ = == = × = mm R m D m D kg m kg m 33 4 3 3 3 3 4 2 6 6 0 0459 1 0 0411 1260 () . (. ) and SG HO kg m m kg 2 3 × = 1260 1000 126 3 . The uncertainty in density is given by % 730 . 0 1 . 41 3 . 0 ; 3 6 3 6 3 % 654 . 0 9 . 45 3 . 0 ; 1 1 4 4 2 1 2 2 ± = ± = = = = ± = ± = = = = +
