If you dropped a rock from a height of 1.1 m on 243 Ida, how long would it take to reach the ground? Express your answer to two significant figures and include the appropriate units. If you can jump 62 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.) Express your answer to two significant figures and include the appropriate units. The asteroid...
