The asteroid 243 Ida has a mass of about 4.0×1016kg and an average radius of about 16 km (it's not spherical, but you can assume it is). Calculate the acceleration of gravity on 243 Ida. What would an astronaut whose earth weight is 700 N weigh on 243 Ida? If you dropped a rock from a height of 2.0 m on 243 Ida, how long would it take to reach the ground? If you can jump 53 cm straight up on earth, how high could you jump on 243 Ida? (Assume the asteroid's gravity doesn't weaken significantly over the distance of your jump.)

The mass of a meteor with a radius of 1 km is about 9 x 1012 kg. The mass of a meteor also is proportional to the cube of its radius. Suppose a meteor with a radius of 8.5 km is moving at 2.0 x 104 m/s when it collides inelastically with the Earth. The Earth has a mass of 5.97 x 1024 kg and assume the Earth is stationary. The kinetic energy lost by the asteroid in this collision...
