(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?

The space shuttle typically travels in a circular orbit at an altitude of 500 km above the Earth's surface. The Earth itself has a radius of about 6400 km. The shuttle can travel in a circular orbit, at constant speed, without any need for the rocket engine to be on, if it travels at just the right speed (a) Given that the value of g is 8.50 m/s2 at an altitude of 500 km, determine the value of the shuttle's...

Consider a very small spacecraft in a circular orbit around the earth. Suppose it is in this orbit for some time, but then, instantaneously, the Earths mass suddenly becomes 50% smaller than it was previously. Determine the resulting orbit of the spacecraft and justify your answer. (note: assume that the only effect on the spacecraft is that it is subsequently moving in the gravitational field of a 50% less massive Earth, and its mass and velocity are the same just...

An orbiting spacecraft is described not as a "zero-g" but rather as a "microgravity" environment for its occupants and for onboard experiments. Astronauts experience slight lurches due to the motions of equipment and other astronauts and as a result of venting of materials from the craft. Assume that a 3500 kg spacecraft undergoes an acceleration of 2.91 µg = 2.85 10-5 m/s2 due to a leak from one of its hydraulic control systems. The fluid is known to escape with...
