Question

Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 22.424 kilometers. The neutron star has mass of 1.5 solar masses (MSun = 1.99 % 1030 kg). What is the local acceleration due to gravity that you experience in your spaceship? Express your answer in m/s2, use scientific notation and round the coefficient to two decimals. B. A 1,895 kilogram satellite is in a low circular orbit about the Earth (i.e. it just skims the surface of the Earth so its orbital distance is practically equal to Earth's radius. We are, of course, ignoring the presence of the atmosphere here). What is the orbital speed of this satellite? The mean radius of the Earth is 6.37 x 106 m. Earth's mass is ME = 5.97x1024 kg. Express your answer in km/s and round it to two decimals. A 1,693 kilogram satellite is in a low circular orbit about the Earth (i.e. it just skims the surface of the Earth so its orbital distance is practically equal to Earth's radius. We are, of course, ignoring the presence of the atmosphere here). What is the orbital period of this satellite? The mean radius of the Earth is 6.37 x 100 m. Earth's mass is ME = 5.97x1024 kg. Express your answer in minutes (enter "min" for minutes) and round it to the nearest integer. D.
