Superman is not immediately concerned, because he knows Zorch can only exert a force of 3.85 x 107 N. For the purposes calculations in this problem you should treat the Earth as a sphere of uniform density even though it isn't. A How long, in seconds, must Zorch push with this force to accomplish his goal? (This period gives Superman time to devote to other villains.)
