Problem

A 2.0 kg2.0\,\text{kg} block sits on top of a 5.0 kg5.0\,\text{kg} block. The surfaces in contact have a coefficient of static friction of 0.40. The table beneath the lower block is frictionless. What is the largest horizontal force that can be applied to the lower block so that the upper block does not slip relative to it? Give your answer in newtons.
