Alight spring with a force coefficient 10.83 n/m is compressed by 12.7 cm as it is held between a 0.29 kg block on the left and a 0.79 kg block on the right, both resting on a horizontal surface. the spring exerts a force on each of the blocks, tending to push them apart. the blocks are then released from rest.
find the acceleration of each block if the coefficient of friction between the blocks and the surface is:
[note: this question may require you to perform your calculations to a few extra digits of precision to get the answer to within 1%.]
(a) μ = 0: right

Arotating space station is said to create “artificial gravity”—a loosely-defined term used for an acceleration that would be crudely similar to gravity. the outer wall of the rotating space station would become a floor for the astronauts, and centripetal acceleration supplied by the floor would allow astronauts to exercise and maintain muscle and bone strength more naturally than in non-rotating space environments. if the space station is 200 m in diameter, what angular velocity would produce an “artificial gravity” of 9.80 m/s^{2} 2 at the rim?
