Two asteroids strike head-on: before the collision, asteroid A (mA = 7.8×1012 kg) has velocity 3.3 km/s and asteroid B (mB = 1.38×1013 kg )has velocity 1.4 km/s in the opposite direction. 1) If the asteroids stick together, what is the magnitude of the velocity of the new asteroid after the collision? 2) If the asteroids stick together, what is the direction of the velocity of the new asteroid after the collision? a. in the original direction of asteroid B...

12. A 500 kg NASA weather satellite is positioned in orbit directly above the USA at a height of 150 km above the Earth's surface. The mass of the Earth is 6 X 1024 kg and its radius is 6,4 X 10° m. What is che gravitational force that keeps the satellite in this position?
In Example 34.6, we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this
In Example 34.6, we imagined equipping 1950DA, an asteroid on a collision course with the Earth, with a solar sail in hopes of ejecting it from the solar system. We found that the enormous size required for the solar sail makes the plan impossible at this time. Of course, there is no need to eject such an object from the solar system; we only need to change the orbit. A much more pressing problem is Apophis, a 300-m asteroid that may be...

Q1. In the old (ish) movie Deep Impact, an asteroid is headed straight for earth at a velocity of 30 km/s! Astronauts try to save the earth by blowing the asteroid into two pieces. One piece is smaller, with a mass of 2.2 x 1013 kg, and the other is 4.7 x 1014 kg. But.... their mission is not successful, and the two pieces remain on the same trajectory, heading straight for earth. A) After the explosion, the smaller piece...

Acceleration due to gravity on board of your spaceship that orbits Jupiter is 25.89 m/s. How high is your spaceship above Jupiter's cloud tops? Express your answer in kilometers and round it to the nearest integer. M Jupiter = 1.90 x 104 kg; R Jupiter = 69,911 km. Your cosmic journey brought you into the vicinity of a neutron star. In fact, you are orbiting this neutron star at an orbital distance of 22.424 kilometers. The neutron star has mass...

The Space X engineering group has been asked to design a mission to send a satellite in orbit around the Earth. The satellite has a mass m_s = 500 kg, and the rocket has a mass m_R = 2000 kg. The satellite is required to revolve with an elliptic orbit around the Earth with velocity v_B = 25 km/s when it is located in point B, at a distance to the earth r_B = 10 Mm. Assuming the mass of...

On February 7, 1999, NASA
launched a spacecraft with the ambitious mission of making a close
encounter with a comet, collecting samples from its tail, and
returning the samples to Earth for analysis. This spacecraft,
appropriately named Stardust, took almost five years to
rendezvous with its objective-comet Wild 2 (pronounced "Vilt
2")-and another two years to return its samples. The reason for the
long round trip is that the spacecraft had to make three orbits
around the Sun, and also...
