A basketball player is standing on the floor 14.5 m away from the basket. The height of the basket is 3.15 m, and he shoots the ball at 42.0° with the horizontal from a height of 1.92 m. At what speed must the player shoot the ball so that it goes through the hoop without striking the backboard?

What are the factors that affect the resistance of a wire?

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?
