- 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?2. Write down the equation for Newton's Law of Universal Gravitation.

- Deepen Lestions: Write FACT if the statement is true and BLUFF if not. 1. The gravitational force exerted by the Earth on an object is equivalent to the object's weight. 2. Gravity is a contact force that acts between two separate objects. 3. Anything that goes up ultimately goes down. 4. The principle of gravity was discovered by Sir Isaac Newton. 5. Gravity on the Moon is greater than on Earth. 6. Gravitational pull between objects increases as the distance between them decreases. 7. The greater the mass of an object, the greater the pull of gravity on it. 8. Mass is the measure of how much matter there is in a body or object. 9. Gravity does not depend on the masses of the object and the distance between two objects. 10. Weight is the force that gravity exerts on an object. ons: Answer the following questions briefly but substantially.
