1. A space station is built in the form of a large circular structure with a radius of 100 m. The rooms of the station are all built such that the outer surface is the floor of each room. How fast would the space station have to spin (in m/sec) for the floor to exert a force on a 75 kg station crew member equivalent to the normal force exerted by a floor on the surface of Earth? 2. The moon rotates around the earth once every 28 days at a radius of 384,000 km. a) What is the speed of the moon in m/s? b) What is acceleration (in m/sec ) the moon experiences
