Tory experiment with pulleys and physics class do you apply 70 N of force to a single pulley to lift a bowling ball by adding another pulley so get a mechanical advantage or two W. a medium and put forestall need to leave the bar she has another polley

Free runners jump long distances and land on the ground or a wall. how do they apply newton’s second law to lessen the force of impact?

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?

For which pair of objects would adding the same a
