Problem 8: Zorch, an archenemy of Superman, decides to slow Earth's rotation to once per 27 h by exerting a force parallel to the equator, opposing the rotation. He uses an old Saturn V rocket, stolen from NASA, which was originally used to send astronauts to the Moon. This rocket can exert a thrust of F = 3.95 x 10' N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. Additionally, use 5.979 x 1024 kg for Earth's mass and 6.376 × 10° m for Earth's radius
