Transcribed Image Text:Would it be possible to launch an object horizontally, near the moon's surface, so
that it orbits the moon? (Let's consider that there is no air resistance there.) Given
that the magnitude of the gravitational field at the moon's surface is approximately
1/6 that at the Earth's surface, determine:
Question 3
a) the centripetal acceleration of that object in orbit;
O 1.6 m/s?
O9.8 m/s?
O4.8 m/s²
O 11.3 m/s?
Question 4 (
b) the speed necessary for the object to orbit the moon. Given: radius of the moon =
1,740 km.
O 1.7 km/s
O 2.6 km/s
1.2 km/s
O 3.2 km/s
