The escape speed from an object is v2 = 2GM/R, where M is the mass of the object, R is the object's starting radius, and G is the gravitational constant 6.67 × 10-11 m3 kg-1 s-2. What is the approximate escape speed, in km/s, from the Solar System starting from an orbit at 0.7 AU? In this case, the mass of the Sun, 2e+30 kg, can be used as the mass of the Solar system.

Constants Part A An asteroid with a diameter of 10 km and a mass of 2.60 x1015 kg impacts the earth at a speed of 32.0 km/s, landing in the Pacific Ocean. If 1 ,00 % of the asteroid's kinetic energy goes to boiling the ocean water (assume an initial water temperature of 10.0 °C), what mass of water wil be boiled away by the collision? (For comparison, the mass of water contained in Lake Superior is about 2 x...

Part A The amount of meat in prehistoric diets can be determined by measuring the ratio of the isotopes nitrogen-15 to nitrogen-14 in bone from human remains. Carnivores concentrate N, so this ratio tells archaeologists how much meat was consumed by ancient people. Suppose you use a velocity selector (Figure 1) to obtain singly ionized (missing one electron) atoms of speed 513 km/s and want to bend them within a uniform magnetic field of 0.510 T....

Part A A 3.7 x 1010 kg asteroid is heading directly toward the center of the earth at a steady 20 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 x 10° N of thrust. The rocket is fired when the asteroid is 4.9 x 106 kmaway from earth. You can ignore the rotational motion of the earth and asteroid around the sun. If the mission...

On Earth, froghoppers can jump upward with a takeoff speed of 2.65 m/s. Suppose some of the insects are taken to an asteroid. If the asteroid is small enough, the froghoppers can jump free of it and escape into space. What is the diameter D1 (in kilometers) of the largest spherical asteroid from which they could jump free? Assume an asteroid density of 1.77 g/cm3. km Suppose that one of the froghoppers jumped horizontally from a small hill on an...
