The Little Prince lives on an asteroid with a radius of 10 km made up of volcanic rock (density 2,500 kg/m3). His mass is 30 kg. a) What is his weight on the asteroid? On Earth he can jump to a height of 1 m. With that knowledge, he jumps up on the asteroid as hard as he can. b) Will he be able to escape the asteroid? The mass of the Earth is 6 x 1024 kg. The radius...

Impacts! The relative velocity of an Asteroid impacting Earth depends on the direction it is approaching Earth’s orbit from. a. Earth’s escape velocity is ~11 km/s, the Earth orbits the sun at ~30 km/s, and an asteroid crossing Earth’s orbit would have about the same velocity of ~30 km/s. What are the minimum and maximum velocities of impact for an asteroid hitting Earth? b. Asteroid 1 with mass m1 hits Earth at a velocity of v1 = 50 km/s. Asteroid...

Calculate the Density of an steroid An extremely massive (spherical) asteroid with a mass of 8.7 x 1015 kg passes through the atmosphere and hits the Caspian Sea. The diameter of the asteroid is determined to be 20.5 km and there are initially 78200 km3 of water in the Caspian Sea. Assuming that this asteroid is denser than water, calculate the water displacement in cubic meter. What is the density of the asteroid in g/cm3? (Hint: use the equation for...

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)...
