Scientists want to place a 4 × 103 kg satellite in orbit around Mars. They plan to have the satellite orbit at a speed of 2330 m/s in a perfectly circular orbit. Here is some information that may help solve this problem:
mmars = 6.4191 x 1023 kgrmars = 3.397 x 106 mG = 6.67428 x 10-11 N-m2/kg2
1.)Which of the following quantities would change the radius the satellite needs to orbit at?
a.)the mass of the satellite
b.)the mass of the planet
c.)the speed of the satellite
2.)What should the speed of the orbit be, if we want the satellite to take 8 times longer to complete one full revolution of its orbit?

- Let gM represent the difference in the gravitational fields produced by the Moon at the points on the Earths surface nearest to and farthest from the Moon. Find the fraction gM/g, where g is the Earths gravitational field. (This difference is responsible for the occurrence of the lunar tides on the Earth.)arrow_forwardCalculate the mass of the Sun based on data for average Earth’s orbit and compare the value obtained with the Sun’s commonly listed value of 1.9891030kg .arrow_forwardA satellite is put in a circular orbit about Earth with a radius equal to one-half the radius of the Moon’s orbit.What is its period of revolution in lunar months? (A lunar month is the period of revolution of the Moon.)arrow_forward
- The Moon has no atmosphere so there is no reason for satellites to orbit very high above it. The highest mountain on the Moon is Mons Hadley at 4.5 km above the lunar surface. If a satellite was orbiting the Moon at an altitude of 4.51 km, how fast would it need to be moving to stay in orbit? You can find data about the Moon in the back endpapers of the textbook or just google what you need.arrow_forwardAn orbiting satellite stays over a certain spot on the equator of (rotating) Earth.What is the altitude of the orbit (called a geosynchronous orbit)?arrow_forwardA satellite orbits in the equatorial plane so that it is always above the same point of Earth's surface.

(The escape velocity for Earth is 11,200m/s.)arrow_forwardLet's say an apple weighs exactly 1N on the surface of the Earth (which corresponds to a distance of 6400 km from the center of the Earth). Now imagine an astronaut brings the apple on a spaceship. What is the force of the Earth's gravity on this apple at a vertical distance of 6400 km above the surface of the Earth? Hint: the radial distance of the apple from the center has doubled. What does this do to the force of gravity according to Newton's law of universal gravitation?arrow_forwardNewton's Law of Gravitation can be used to show that if an object weighs w pounds on the surface of the earth, then its weight at a distance x from the center of the earth is W(x) : wR? (for x > R), where R = 3960 miles is the radius of the earth. Estimate the weight loss per mile of altitude gained for a 205-lb pilot at an altitude of h. (Use decimal notation.
