Thank you for the question!
According to the the formula P=F\A,there is an inverse relation between pressure and area. If area will be more than less pressure will be generated or applied and vice versa. By applying this theory the area of the sharp nail is less so it will exert more pressure in the wood and it will easily get immersed into the wood. Wile the blunt nail has more area thus it will exert less pressure. That''why its easier to hammer sharp nail.
Hope it helps.
