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?
a. Calculate the gravitational force of attraction between the Earth and the Sun if the Sunhas a mass of 1.989 x 1030 kg and is a distance of 149.6 million kilometres from theEarth. b. How would you expect the gravitational force between you and your friend tocompare to your answer from question 1 if you stood 1 metre apart? Explain.

The gravitational force of attraction between any two point masses is attractive and the magnitude: Gm₂m₂ G = 6.67 x 10-11 N-m² kg² F= where G is the gravitation constant, m, and m₂ are the masses, and r is the distance between the masses. This is quite different from the force of gravity that we have been using, where weight = mg. 1. Acceleration due to gravity: a. Lett one mass be the Earth and the other mass m is let go just above the surface of the Earth. Calculate the value of the acceleration due to gravity using Newton's law of gravitation. The net effect of the Earth's gravity is the same as if the all the mass of the Earth were concentrated at its center. b. The F-22 Raptor fighter jet has a service ceiling of 12 miles or 20 km. Determine the acceleration due to gravity at this altitude. c. The International Space Station is in low Earth orbit at a height of 400 km above the surface of the Earth. Determine the acceleration due to gravity at this altitude. d. What is assumed…
A planet has 1/9 the earth's mass and half its radius. It orbits a star with six times the sun's mass with an orbital period of 48 years. Suppose aliens from this planet crash their spaceship in New Mexico. If the spaceship weighs 1200 Zorgs on their planet, then what is the weight in New Mexico, in Zorgs? I got 533.3 Zorgs but it was incorrect.
Three 10 kg masses are located at distances d1=0.25 m and d2=0.35 m. What are... a. The magnitude and direction of the net gravitational force on A due to both B and C? b. Write the net gravitational force in unit vector notation. c. At what position would you put a 20 kg mass if you wanted the net force on A to be zero, all other masses and positions remaining the same?
Using SI units. Determine the gravitational force acting between two spheres that are touching each other. The mass of each sphere is 200 kg and the radius is 300 mm. Give your answer in micro-netwons (µN) and to three significant figures.

Earth is the third planet in our solar system. If Earth became the fifth planet in our solar system, how would that affect the gravitationallforce? A. The gravitational force would increase. B. The gravitational force would decrease. C. The gravitational force would remain the same. D. The gravitational force would not change .
