- Assume you are the lead Physicist at SpaceX and you are asked to calculate the gravitational force that will be acting on a new satellite they plan to launch into space to orbit Mars. Calculate the force between Mars, which has a mass of 6.39*1023 kg, and the satellite, which has a mass of 420 kilograms. Assume that NASA wants the satellite to orbit Mars at a distance of 20,775 meters. G = 6.67 x 10-11 N\cdot⋅m2/kg2 Answer in scientific notation ( #*10^#) Answer with 3 significant figures Do NOT include units in your responseIt is interesting to note that there is a big difference in size between the space craft required to leave the Earth and a space craft required to leave the Moon.

- Use Kepler's third Law to determine how many days it takes a spacecraft to travel in an elliptical orbit from a point 6670 km from earth's center to a point 385,000 km from earth's center(the mass of earth is 5.97*10^24 kg).Question 1. Calculate the speed of a satellite (mass of 1500kg) that orbits Mars at an altitude of 400 km.A satellite is orbiting the earth in low orbit (160 km above the surface of the earth). If the universal gravitational constant is 6.67 x 10^-11 m^3/kg x s^2 the mass of the earth is 5.972 x 10^24 kg and the radius of the earth is 6371 km, what speed must the satellite travel in order to maintain the low earth orbit?
