I have no idea how to physics so I decided to ask some people. I want to know what the effects of a very high speed pebble would be. Can someone explain what would happen if a sphere of density 2.5 g/cm3 and radius 1.5cm moving at 700 m/s were to collide with A: a stationary wall of insect carapace 3 cm thick? B: a stationary wall of mammal flesh 10 cm thick? C: a stationary wall of steel 2 cm thick?
