A person is in the international space station 400km above the surface of the Earth. (Radius of Earth 6,371 km, Mass of Earth 5.972 x 1024kg, G = 6.674 x 10-11 m3/(kg.s))

a) What is their free-fall acceleration? b) If an astronaut outside the space station were to drop a ball with a 5cm diameter which had a drag coefficient of 0.6 and a density of 0.4 x 103 kg/m3, what would its terminal velocity be when it is close to the surface of the Earth? (density air 1.29 kg/m3)(Vsphere= 4/3(pi)(r3)

    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...

    10) The international space station (ISS) orbits the Earth from an altitude of 408 km. a) Calculate the strength of Earth’s gravity on the ISS at that altitude. (Hint: How far is the ISS from the center of mass of the Earth?) b) Earth’s gravity is what keeps the ISS in its orbit (which we will assume is circular). At what speed does the ISS orbit the Earth? Please show working New Equations 2 torque = (lever arm) x (force)...

    A space station is orbiting the Earth. It moves in a circular orbit with a radius equal to three times the Earth's radius. A supply satellite is designed to travel to the station and dock smoothly when it arrives. If the supply satellite is fired as a simple projectile from the Earth's surface, what is the minimum intial speed required for it to reach the space station and have a speed equal to the station's speed when it arrives? Ignore...

    The space station orbits Earth about 400 km above the surface of Earth (NASA.gov). At this height the force of gravity from Earth is only about 10% less than on the surface of Earth. Using the concepts of circular motion and gravitational forces explain the following: 1. Why does the space station not fall down? 2. Why do the astronauts float inside the space station?
