Apuck rests on a horizontal frictionless plane. a string is wound around the puck and pulled on with constant force. what fraction of the disk's total kinetic energy is due to the rotation? kerot/ketot

In order for the bug to fly through the air a force has to push the bug forward. identify this force. how does the bug produce

What is the magnitude of the resultant vector round your answer to the nearest tenth

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?
