A shuttle is being launched off a planet that has no air. The planet has a radius of 4.44×106 m and a mass of 4.30×1024 kg. The shuttle is fired off the planet at a speed of 9.60×103 m/s. A small satellite is orbiting 570. m above the planet. What is the speed of the shuttle as it passes the satellite?

4. A space probe is orbiting Planet A. It is then moved into an orbit around Planet B. Planet B has three times the mass of Planet A, and the probe’s orbit around Planet B is twice the radius of the orbit it had around Planet A. What is the ratio of the orbital period around Planet B to that around Planet A? A. 2.0 B. 0.62 C. 1.6 D. 0.82 E. There is not enough information to answer.

Suppose there is a planet orbiting close to a black hole, as Earth is to the Moon. There is an ocean on that planet. If you happen to be there, what would you notice? Select one: a. The ocean has tides, but only once per day, unlike Earth when we have them twice per day b. The ocean has tides, but they are way higher than on Earth c. The ocean has tides, but they are way smaller than on...

Two space ships collide in deep space. Spaceship P, the projectile, has a mass of 5M, while the target spaceship T has a mass of M. Spaceship T is initially at rest and the collision is elastic. If the final velocity of T is 5.6 m/s, what was the initial velocity of P?

Prelecture Exploration: Gravitational Forces Mika is interested in the story of Isaac Newton, who, she has read, might have seen an apple falling from a tree or perhaps was hit on the head by one. That apple and seeing the Moon were supposedly what led him to think up and to develop his theory of universal gravitation. She and her friend Esperanza are intrigued with Newton's discovery that the same force that causes apples to fall is responsible for the...

1. An undiscovered planet, many lightyears from Earth, has one moon in a periodic orbit. This moon takes 1660× 103 seconds (about 19 days) on average to complete one nearly circular revolution around the unnamed planet. If the distance from the center of the moon to the surface of the planet is 235.0 × 106 m and the planet has a radius of 3.10 × 106 m, calculate the moon's radial acceleration ?cac. 2. In a laboratory test of tolerance...

Gravitational Potential Energy Planet X is composed of material that has a mass density rho. It has a radius of R. When a space Probe of mass m is a distance of r from the center of planet X, it has a speed of v moving straight away from the planet. (a) What speed will the probe have (in the absence of any booster rockets) when it moves out to a distance of 2r? (b) What is the escape velocity...

Question 7 (0.5 points) What causes the Moon to move about 12° across the sky from one night to the next (at the same time of night, of course)? O Because the Earth is turning on its axis. O Because the Moon is moving in its orbit. The Sun has also moved 15° across the sky and gravitationally pulls the Moon with it. The celestial sphere the Moon is attached to has moved 15°. O It is an optical illusion....

Question 4 20 pts A probe is orbiting a distant moon. The moon has a mass of M = 5.0 x 1022 kg and a radius of R= 1.5 x 106m. The probe makes one revolution every 6 hours. a) Find the distance the probe is above the surface of the moon. b) At what minimum velocity would would a rocket launched from the surface of the moon be able to reach a distance of 2.2 x 10m from the...
