1 Point A space station is shaped like a wheel of radius $$R$$. By making the station rotate, the gravitational acceleration on Earth can be simulated. A space station is shaped like a wheel of radius $$R$$. By making the station rotate, the gravitational acceleration on Earth can be simulated. So if an astronaut steps on a scale, the reading on the scale is $$mg$$. a. What constant angular speed $${?}_0$$ needs to be given to the station such that the gravitational acceleration on Earth is simulated? b. The station is initially rotating with angular speed $${?}_0$$. At time $$t=0$$ the station needs to go into emergency shutdown and the rotation is slowed down with a constant angular acceleration of magnitude $${?}_c$$. Astronaut Jose had just placed a wrench of mass $$m$$ onto a workbench where it has a coefficient of static friction $$?$$. At what time $$t_1$$ does the wrench start to slip against the table?
