A mysterious, newly discovered planet has a radius of 8500 km and a mass of 9.5 x 1023 kg. Suppose you want to launch a satellite into a circular orbit around this planet to observe its surface features. The satellite is to have an altitude of 750 km above the surface of the planet. (a) With what speed should the satellite be launched (in km/s)? (b) What is the orbital period (in hours)? 750 8500 km km
