A hockey puck of mass 0.44 kg is shot east at 2.00 m/s strikes a second puck, initially at rest, of mass 0.58 kg. As a result of the collision, the first puck is deflected at an angle of 31° south of east, with a speed of 1.15 m/s. What is the speed of the second puck after the collision?

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?
