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

2.22/3.33 points | previous answers tamucolphysmechl1 4.pre.002. ask your teacher my notes question part points submissions used on a frictionless air track, a blue glider with mass 0.200 kg is moving to the right with a speed of 8.00 m/s. it strikes a red glider that has mass 0.600 kg and that is initially at rest. after the collision, the blue glider is moving to the left with a speed of 2.40 m/s. (a) what are the magnitude and direction of the velocity of the red glider after the collision? magnitude 3.33 m/s correct: your answer is correct. direction correct: your answer is correct. (b) is this collision elastic?
