Questions:
1) Calculate the orbital velocity of the Earth around the Sun given the following information:
Mass of the Earth = 6.0 × 1024 kg
Mass of the Sun = 1.99 × 1030 kg
Average Sun – Earth distance = 1.5 × 1011 m
2) A 200kg satellite orbits Mars at an altitude of 350km. Use the following information to calculate:
Mass of the Mars, MM = 6.42 × 1023 kg
Radius of the Mars, rM = 3390 km
a) the orbital velocity of the satellite:
b) the period of the satellite:
c) what happens to the orbital velocity and the period if the mass of the satellite is doubled?
3) An Earth satellite has an orbital velocity of 10000 km/hr. Calculate the altitude of this satellite given:
Mass of the Earth, ME = 6.0 × 1024 kg
Radius of the Earth, rE = 6.371 × 106 m
