Simulаting аrtificiаl gravity оn vоyages tо Mars can be achieved by a spaceship rotating at a constant angular velocity. What is the linear speed on a point on the rim of this rotating spaceship with radius R=[R] m, such that the astronaut experiences an artificial gravity equal to half of the weight she would experience on Earth's surface?
