4. A student feels a gravity force of 800 N from the Earth when they're sitting in this classroom. a. How big is the gravity force that the Earth feels because of the student? Explain. b. Two students discuss part a). Student 1: "The Earth is much heavier than the student, so its gravity must pull harder on the student than the student's gravity pulls on the Earth. The gravity force the Earth feels must be less than 800 N." Student 2: "That might be true, but I think that same 800 N would have less of an effect on the Earth than it would on a person. Using a = F/m, the acceleration the Earth feels might be very small from an 800 N force, because Earth is so heavy." Which of these students, if any, do you agree with? Justify your response with words and/or equations.

A mountain 10.0 km from a person exerts a gravitational force on him equal to 2.00 of his weight. (a) Calculate the mass of the mountain. (b) Compare the mountain’s mass with that of Earth. (c) What is unreasonable or inconsistent? (Note that accurate gravitational measurements can easily detect the effect of nearby mountains and variations in local geology.)
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?
Unreasonable Result A mountain 10.0 km from a person exerts a gravitational force on him equal to 2.00% of his weight. (a) Calculate the mass of the mountain. (b) Compare the mountain's mass with that of Earth. (c) What is unreasonable about these results? (d) Which premises are unreasonable or inconsistent? (Note that accurate gravitational measurements can easily detect the effect of nearby mountains and variations in local geology.)
Astronomical observatrions of our Milky Way galaxy indicate that it has a mass of about 8.01011 solar masses. A star orbiting on the galaxy’s periphery is about 6.0104 light-years from its center. (a) What should the orbital period of that star be? (b) If its period is 6.0107 years instead, what is the mass of the galaxy? Such calculations are used to imply the existence of other matter, such as a very massive black hole at the center of the Milky Way.
1. Is it accurate to say that astronauts in the International Space Station orbiting the Earth, are able to float and bounce around the station because they are in zero gravity? Why or why not? 2. If I stand a certain distance from an object, and our gravitational force is some unknown value F, how will that value change if I go twice as far away from the object as I started? Will the gravitational force now be twice as strong, half as strong, or something else? Explain your answer.
An astronaut with a mass of 100 kg is traveling in a space station moving in an Earth orbit. (A) What is the speed of the space station? (b) What is the weight of the astronaut?
What is altitude of a 1000.0 kg satellite orbiting the Earth where the gravitational field strength is 6.54 m/s2? B) Explain how the gravitational field strength AND Force of gravity would differ or be similar for a 10 kg satellite versus a 1000 kg satellite at the same radius found in part A. Use numbers to verify your explanation.
800 lb space probe is launched from Earth, headed for deep space. a) List the correct equation and solve for mass given that the acceleration of gravity is 32.2 ft/s2 b) At a distance of 15,000 miles from the Earth's center, the space probe releases a payload that reduces the mass of the space probe by 1/4th (i.e., space probe is now 25% lighter in mass). By how much did the gravitational force go up or down after the payload has been released? Start with the equations from the text or class notes and solve.
1) Calculate the tidal force (the difference in gravitational force from right to left side or G(R) - G(L) ) from a person sitting next to you (approximately 1 meter away). You will need to make some estimations on mass and size of a normal person. 2) Compare the tidal force on a person from the Moon and a person standing nearby (the answers to the previous two questions). Which is greater and by how much?
The Cavendish experiment marked a milestone in the study of gravity. Part A. What important value did the experiment determine? Part B. Why was this so difficult in terms of the masses use in the apparatus and the strength of the gravitational force?

An adventurous archaeologist crosses between two rock cliffs by slowly going hand-over-hand along a rope stretched between the cliffs. He stops to rest at the middle of the rope (Figure 1). The rope will break if the tension in it exceeds 2.55×104 NN , and our hero's mass is 87.6 kgkg1. If the angle between the rope and the horizontal is θθtheta = 11.1 ∘∘, find the tension in the rope?2. What is the smallest value the angle θθ can have if the rope is not to break?
