Impact depth etc

  1. Dec 15, 2006 #1
    If 1kg piece of steel hits steel surface with speed of 5m/s, how can you
    calculate the depth of the impact? Let's assume that the steel has
    0.345 kN/mm2 material shear strength.

    Second question is that how much speed is needed to that same steel piece
    to penetrate 1cm thick steel sheet (using the same shear strength), and
    what's the speed of the 1kg steel piece after the penetration?
