1. What is the acceleration due to gravity on the surface of Mars? The mass of Mars is 6.418X1023 kg and its radius is 3.38X106 m . calculate the gravitational force exerted on a 4.20 kg baby by a 100kg Tather 0.200 m away at birth (he is assisting, so he is close to the child). 3. Two spherical objects have masses of 200 kg and 500 kg. Their centers are separated by a distance of 25 m. Find the gravitational attraction between them. 4. Planet X has a gravitational acceleration of 7.5 m/s2 and radius 4.5 x 106 m.What is the mass of planet X?
