WebNov 22, 2024 · I have found that the vis-viva equation is used to calculate the velocity of an object on an elliptical orbit and that the perihelion is at distance r = a (1-e). However I (simply enough) cannot see how to mathematically combine these two pieces of information in order to get the velocity at the perihelion. Web(a) Calculate Earth’s mass given the acceleration due to gravity at the North Pole is measured to be 9.832 m/s 2 and the radius of the Earth at the pole is 6356 km. (b) Compare this with the NASA’s Earth Fact Sheet value of 5.9726 × 10 24 kg. 21. (a) What is the acceleration due to gravity on the surface of the Moon? (b) On the surface of Mars?
