- According to the National Academy of Sciences, the Earths surface temperature has risen about 1F since 1900. There is evidence that this climate change may be due to human activity. The organizers of World Jump Day argue that if the Earth were in a slightly larger orbit, we could avoid global warming and climate change. They propose that we move the Earth into this new orbit by jumping. The idea is to get people in a particular time zone to jump together. The hope is to have 600 million people jump in a 24-hour period. Lets see if it will work. Consider the Earth and its inhabitants to make up the system. a. Estimate the number of people in your time zone. Assume they all decide to jump at the same time; estimate the total mass of the jumpers. b. What is the net external force on the Earthjumpers system? c. Assume the jumpers use high-tech Flybar pogo sticks (Fig. P8.32), which allow them to jump 6 ft. What is the displacement of the Earth as a result of their jump? d. What happens to the Earth when the jumpers land?arrow_forward17. One of Kepler's Laws states that: a.

- Galileo conducted an experiment where he rolled different balls down an inclined plane. Galileo determined that each ball traveled a distance that was directly proportional to the square of the time it traveled. What did Galileo conclude from this experiment? A.

The force of friction from the inclined plane causes a decrease in the acceleration of an object.arrow_forward1. Which statement about Issac Newton is not true? A.
