Sally swings a 0.45 kg hammer with a speed of 5 m/s, striking the head (flat back end) of a metal nail with its tip (sharp front end) resting on an oak wood surface. The tip of the metal nail has an area of 3 mm2 and the duration of the impact is 5.0 ms. The wood has a ultimate compressive strength of 6 MPa. Calculate the pressure applied by the tip of the nail onto the wood surface. Will the nail penetrate the wood
