Let's consider an astronaut with a mass of 76.0 kg standing on the Earth. What is the gravitational force (in N) on the astronaut? (Review your work from the previous part. Remember that you can use the full gravitational force formula, or w = mg.) weight on the Earth's surface = 744.8 N Now let's imagine that same astronaut in orbit aboard the space station, orbiting at an altitude (height above the Earth's surface) of 380 km. We first need to find the astronaut's distance to the center of the Earth. What is the altitude expressed in units of meters? 380 km = 380000 The radius of the Earth is 6.37 ✕ 106 m. What is the total distance (in m) from the center of the Earth to the astronaut? r =_________m Finally, let's put it all together. Use the universal gravitational force formula to find the force (in N) on the astronaut, where m = 76.0 kg, the Earth's mass ME = 5.97 ✕ 1024 kg, and the distance r is the result you just found. F = ______N solve for the two bolded…
