Unit 8 Worksheet 3

1.      The gravitational field strength on the moon, which has a radius of 1.74 Mm, is approximately 0.17 as large as the gravitational field strength at the surface of the earth. How much would a 1500 kg satellite weigh at the surface of the moon?

         Assume that the diagram below represents the orbit, around the moon at an altitude of 1.00 km, of the satellite in question #6.

2.      Construct a force diagram of the satellite in orbit.

3.      Demonstrate the direction of the acceleration, if any, by means of a motion map.

4.      What is the radius of the orbit of the satellite described in problem #3?

5.      What would be the orbital period of the above satellite?

6.      What is the orbital speed of the satellite described in the preceding problems?

7.      Is this satellite being accelerated? If so, what is the direction and magnitude of the acceleration?
