What is the approximate value of the gravitational force between a 72 kg astronaut and a 7.8 metric ton spacecraft when they are 72.5 m apart?
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...

(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?
Two uniform metal spheres with masses of 100kg and 150kg have radii of 6.0 cm and 8.0 cm, respectively. If their surfaces are separated by a distance of 0.86 m, what is the gravitational force of attraction between the spheres?
An astronaut is connected to her spacecraft by a 27-m-long tether cord as she and the spacecraft orbit Earth in a circular path at a speed of 3.1 103 m/s. At one instant, the voltage measured between the ends of a wire embedded in the cord is measured to be 0.40 V. Assume the long dimension of the cord is perpendicular to the vertical component of Earth's magnetic field at that instant. (a) What is the magnitude of the vertical...
An astronaut in her space suit has a total mass of m, = 90.0 kg, including suit and oxygen tank. Her tether line loses its attachment to her spacecraft while she's on a spacewalk. Initially at rest with respect to her spacecraft, she throws her oxygen tank of mass m, - 12.0 kg away from her spacecraft with a speed v = 7.50 m/s to propel herself back toward it (see figure). (a) Determine the maximum distance she can be...
