The asteroid 243 Ida has a mass of about 4.0 × 10 16 kg and an average radius of about 16 km (it’s not spherical, but you can assume it is). (a) Calculate the acceleration of gravity on 243 Ida. (b) What would an astronaut whose earth weight is 650 N weigh on 243 Ida? (c) If you dropped a rock from a height of 1.0 m on 243 Ida, how long would it take for the rock to reach the ground? (d) If you can jump 60 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.)

Consider the gravitational acceleration on the surface of the Moon and of Mars.
a) What is the acceleration, in meters per square second, due to gravity on the surface of the Moon? You will need to look up the mass and radius of the Moon.
b) What is the acceleration, in meters per square second, due to gravity on the surface of Mars? The mass of Mars is 6.418 × 1023 kg and its radius is 3.38 × 106 m.
Given: the radius of the moon is 1,080 miles
Many people mistakenly believe that astronauts that orbit the Earth are "above gravity." Calculate the acceleration due to gravity (g) for space shuttle territory, 200 kilometers above the Earth's surface. Earth's mass is 6 x 1024 kilograms and its radius is 6.38 x 106 meters (6380 kilometers). Your answer is what percentage of 9.8m/s2?
