Zorch, an archenemy of Superman, decides to slow Earth’s rotation to once per 29 h by exerting a force parallel to the equator, opposing the rotation. Superman is not immediately concerned, because he knows Zorch can only exert a force of 4.15 × 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.)

A team of professional thieves wants to knock down a castle wall using a primitive explosive. At theirheadquarters, they determine that the explosive has a mass of 40.0 kg and will break into three pieces: a 20.0 kgpiece will go exactly east, a 10.0 kg piece will go exactly south, and a 10.0 kg piece will go somewhere. Find thespeed and direction of the third piece of the explosive.
