1. Consider a space shuttle which has a mass of about 1.0 x 105 kg and circles the Earth at an altitude of about 20.0 m. Calculate the force of gravity that the space shuttle experiences. The mass of the earth is 2. What is the gravitational force between two identical 500 kg asteroids whose centers of mass are separated by 1000 m? 3. If you have a mass of 150 kg and you are standing 5 meters away from your car, which has a mass of 10 kg, how strong is the force of gravity between you and the car? 4. The moon has a mass of 7.34 103 kg and a radius of 1.50 102 meters. If you have a mass of 120kg, how strong is the force between you and the moon? 5. Romeo is a 68 kg astronaut. Juliet is a beautiful cosmonaut who is standing on the balcony of a 4.58 105 kg space station that is at rest and out of gas. Romeo is oating 25 meters away from the space station's center of mass, how strong is the force between Romeo and Juliet
