You have negotiated with the Omicronians for a base on the planet Omicron Persei 7. The architects working with you to plan the base need to know the acceleration of a freely falling object at the surface of the planet in order to adequately design the structures. The Omicronians have told you that the value is gOP7=7.29 flurg/grom^2, but your architects use the units meters/second^2, and from your previous experience you know that both the Omicronians and your architects are terrible at unit conversion. Thus, it's up to you to do the unit conversion. Fortunately, you know the unit equality relationships: 5.24flurg=1meter and 1grom=0.493second. What is the value of gOP7 in the units your architects will use, in meter per second squared?
You are on a planet and drop an object from a height of 2 meters and it takes 3 seconds to hit the ground. What is the acceleration of gravity on the planet's surface and how fast was it moving when it hit the ground?
The International Space Station (ISS) orbits Earth in a nearly circular orbit that is 345 km above Earth's surface.
1)
How many hours does it take for the ISS to make each orbit? (Express your answer to three significant figures.)
2)
Some of the experiments performed by astronauts in the ISS involve the effects of "weightlessness" on objects. What gravitational force does Earth exert on a 12.0-kg object in the ISS? Express your answer in newtons. (Express your answer to three significant figures.)
3)
What gravitational force does Earth exert on a 12.0-kg object in the ISS? Express your answer as a fraction of the force that Earth would exert on the object at Earth's surface. (Express your answer to three significant figures.)

- 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_forwardCalculate the minimum amount of work needed to move a 400 kg rocket from Earth's surface to the International Space Station in orbit 300,000 m above Earths surface. Solve for the minimum amount of work needed to move the payload to the ISS. Start with general equations and explain what you are doing and why you did what you did. Evaluate your solution. Describe how you evaluated your answer and whether or not you think your answer is reasonable.arrow_forwardI am stuck on where to start with this question... 2. a. For two moons, (Moon A and Moon B) with the same mass, both in circular orbits about Mars, how many times more quickly or slowly is Moon B moving along its orbit if it 9 times farther from Mars' center than Moon A? b. Now if Moon A is 4 times more massive that Moon B, how much faster or slower will Moon B's orbital velocity be (relative to that of Moon A)?arrow_forward
- The gravity on Mars is about 38% that of Earth's gravity. Let's say some cargo has a mass of 15 kg here on Earth. First, what would be the weight of that cargo in kilograms on Mars?

Sketch a diagram including Earth, Sun, and Mars, with attention to scale of distance (Mars is about 1.5 AU from the Sun) showing a faster trajectory from Earth to Mars than the minimal energy trajectory discussed in the lecture. b. Without doing a calculation, how would the arrival velocity of the spacecraft at Mars for the case in (a) compare to the spacecraft arrival in the class example? The lecture example had the spacecraft arriving at Mars with a velocity of 22.49 km/sec. c. The average velocity of Mars in orbit around the Sun is 24.08 km/sec. Comment on the trade-offs between trajectories, arrival velocities and velocity changes (delta V) required to enter an orbit around Mars.arrow_forwardNASA is planning a space station that will have artificial gravity. The plan is for a 250 m radius. NASA wants the acceleration at the outer edge to be 4.9 m/s2. Calculate the velocity of the station’s rotation. The station will be equipped with a launcher at the end of each spoke. Choose the diagram that shows the direction a small spaceship will go when it is released from the station, and note how fast it will go.arrow_forward

In what way(s) is Einstein's general theory of relativity superior to Newton's theory of universal gravitation? For each way, give an example of a case where Einstein's theory provides a more accurate description of physical phenomena than does Newton's. (Select all that apply.) A.) Newton's theory originally held that the orbit of a spherical object about another will be an open curve for which the point of closest approach slowly precesses. Einstein's theory correctly predicts that gravitational forces lead to orbits of closed ellipses. B.) Einstein's theory correctly predicts the deflection of light passing near a massive object, while Newton's theory predicts a deflection that is one-half the observed deflection. C.)
