Homework Help: physics

Posted by Steven on Monday, July 29, 2013 at 5:37am.

Our muscles atrophy when there is no gravitational force. On long space flights this is a problem, which is why astronauts exercise. On very long space flights it might be advisable to simulate gravity. Your space ship is a long cylinder of radius 100 m that spins about its axis. What angular velocity in rad/s for the spin is needed so that the force felt by a person standing on the rim of the cylinder matches the force of gravity felt on Earth?

take g=-9.8m/s^2
