A 3.9×1010kg asteroid is heading directly toward the center of the earth at a steady 22 km/s. To save the planet, astronauts strap a giant rocket to the asteroid perpendicular to its direction of travel. The rocket generates 5.0×109N of thrust. The rocket is fired when the asteroid is 3.8×106km away from earth. You can ignore the rotational motion of the earth and asteroid around the sun. Express your answers to two significant figures and include the appropriate units. a)...

7. Two satellites are moving around Earth following orbits of the same radius. Satellite 1 has mass equal to half of mass of satellite 2. We can conclude that: Speed of satellite 1 is twice as big as speed of satellite 2. Speed of satellite 1 is half of speed of satellite 2. Speed of satellite 1 is the same as speed of satellite 2. Speed of satellite 1 in fours times speed of satellite 2. Speed of satellite 1...
