Find how long zorch must push with this force

Reference no: EM13334179

Zorch, an archenemy of Superman, decides to slow the earth's rotation to once per 31.0 h by exerting an opposing force at the equator and parallel to it. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.00 ? 107 N (comparable to a Saturn V rocket's thrust). Assume the earth's initial rotation is exactly once per 24.0 h and use energy considerations to find how long Zorch must push with this force to accomplish his goal. (This gives Superman time to devote to other villains.)
