A tomato is travelling very fast towards a 1 cm thick steel plate.
Let's say this happened in a vacuum, so that the air resistance wouldn't rip the tomato apart before it even hit the steel plate.
Obviously the tomato would get destroyed too, but the question is whether there would be a hole in the steel plate, given enough speed.
I guess a more general way to phrase the question is: Can a soft object create a hole through a hard surface, as long as the soft object is traveling fast enough?
If yes, is there a limit to this concept? For example, could the tomato even penetrate a wall made of diamond, as long as it was traveling fast enough?
Edit: A comment on one of the answers used this video to show that tomatoes can't exist for very long in a vacuum. If this is correct, the situation needs to be that the tomato is stationary, the plate moves, and the tomato is put into the vacuum shortly before impact. I believe the impact scenario would be the same in that case?
