3. Imaging another one planet with an acceleration of 10.00 m/s^2 at its equator when ignoring the rotation of the planet. The radius of the planet is 6.2*10^6 m. An object dropped at the equator yields an acceleration of 9.70 m/s^2. What is the length of one day on this planet? [7.9 h] 5. In theory, if a car went fast enough it could fly out of earth's surface. This is because at a fast enough speed, earths gravity is not strong enough to pull the car in a circle with a radius equal to the radius of the earth. How fast must a car go for this to happen? [7.9*10^3 m/s] Please explain all steps
