A 5.30 g bullet moving at 963 m/s strikes a 610 g wooden block at rest on a frictionless surface. The bullet emerges, traveling in the same direction with its speed reduced to 426 m/s. (a) What is the resulting speed of the block? (b) What is the speed of the bullet-block center of mass?
Answers: 1
= 4.67m/s
are the mass and the initial velocity of the bullet, 
and 
are the mass and the initial velocity of the wooden block, and 
are the final velocities of the wooden block and the bullet
this yields

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?
