A 100kg astronaut floats at a distance of 15 m from a 60,000 kg spacecraft. What is the force of attraction between the astronaut and spacecraft?
The magnitude of the tidal force between the International Space Station (ISS) and a nearby astronaut on a spacewalk is approximately 2GmMa/r3 . In this expression, M is the mass of the Earth, r=6.79×106m is the distance from the center of the Earth to the orbit of the ISS, m=125kg is the mass of the astronaut, and a=20m is the distance from the astronaut to the center of mass of the ISS. Calculate the force of gravitational attraction between the...

An 97 kg spacewalking astronaut pushes off a 685 kg satellite, exerting a 97 N force for the 0.5 s it takes him to straighten his arms. a. What impulse is delivered to the astronaut from the satellite? kg m/s b. What's the speed of the astronaut after he pushes off? (We'll call the astronaut and satellites initial velocity 0.) m/s c. What's the speed of the satellite after the astronaut pushes off? m/s d. How far apart are the...
(1) You are an astronaut in a spacecraft that is orbiting Earth in a circular orbit at a constant rate of one orbit every 90 minutes. Are you accelerating? Explain. If you are accelerating, what is the direction of the acceleration? (2) Astronauts are said to be "weightless" as they orbit the Earth. Does the astronaut m question #4 experience a gravitational force due to the Earth? If there is a force, what is the direction of the force?
