Explanation / Answer

mass m = 1.5 * solar mass             =1.5 * ( 1.98892 × 1030 kilograms ) * 100 /0.135 radius R = 8 km = 8000 m (a). accleration due to gravity g = Gm / R 2 (b). the weight of a 0.123 kgbaseball on this star is W = M g where M = 0.123 kg (c). the energy that a 69.0 kgperson would expend climbing a 1.00 cm tall mountain on the neutronstar = 69 * g h where h = height = 1 cm = 0.01 m substitue values weget answers (b). the weight of a 0.123 kgbaseball on this star is W = M g where M = 0.123 kg (c). the energy that a 69.0 kgperson would expend climbing a 1.00 cm tall mountain on the neutronstar = 69 * g h where h = height = 1 cm = 0.01 m substitue values weget answers
