A person riding a bike has a total mass of 95 kg, if the person bike system is moving at a velocity of 5 m/s, how much kinetic energy is there?

Avalue that describes how heavy an object is and is related to the force of gravity is

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?
