Problem 2: The acceleration due to gravity on a celestial body as a function of altitude is given by the expression: g = 4 - 1.6 x 10-6h m/s² for a planet, where h is in m above the surface of the planet. The volume of the body is 1.36 m³ and the average density is 7500 kg/m³. Find: a) the mass of the body b) the weight of the body on the surface of the planet c) the weight of the body at an elevation of 200 km above the surface of the planet
