If object 2 weighs 52 lbs, calculate the minimum weight of object 1 such that object 2 can be kept from moving, accurate to 1lb.

If object 2 weighs 52 lbs, calculate the minimum weight of object 1 such that object 2 can be kept from moving, accurate to ±1lb.  Assume the coefficient of static friction is the same for all surfaces in contact, and is 0.3.
