When it hails, each golf ball-sized chunk of hail rained down with a mass of 0.025 kg mass and impacted my car with a velocity of 400 m/s. The hood of the car is made out of 1040 steel. The modulus of elasticity is 207 GPa, the YS is 490 MPa, and the UST is 590 MPa. A. Determine the amount of energy (or work) that the steel hood of my car could absorb before being Plasticly deformed. Assume that the cross-sectional area impacted by the hail is 0.0005 m2 and that the thickness of the steel is 0.005 m. B. Determine the amount of energy (or work) that the steel hood of my car could absorb before being fractured. Assu
