Question
Nail tips exert tremendous pressures when they are hit by hammers because they exert a large force over a small area. What force must be exerted on a nail with a circular tip of 1.00 mm diameter to create a pressure of $3.00 \times 10^9 \textrm{ N/m}^2$ (This high pressure is possible because the hammer striking the nail is brought to rest in such a short distance.)

$2360 \textrm{ N}$
