Question

One problem for humans living in outer space is that they are apparently weightless. One way around this problem is to design a space station that spins about its center at a constant rate. This creates "artificial gravity" at the outside rim of the station.

Part A

If the diameter of the space station is 830 m, how many revolutions per minute are needed for the "artificial gravity" acceleration to be 9.80m/s29.80m/s2?

Part B

If the space station is a waiting area for travelers going to Mars, it might be desirable to simulate the acceleration due to gravity on the Martian surface (3.70m/s2)(3.70m/s2). How many revolutions per minute are needed in this case ?
