A space habitat for a long space voyage consists of two cabins each connected by a cable to a central hub as shown in the figure below.The cabins are set spinning around the hub axis, which is connected to the rest of the spacecraft to generate artificial gravity.

(a) What forces are acting on an astronaut in one of the cabins?

(b) Write Newton's second law for an astronaut lying on the "floor"of one of the habitats, relating the astronaut's mass m,his velocity v, his radial distance from the hubr, and the normal force n.
