How do I push the player away from a block when jumping into it?

Let me explain in more detail. I was making test game and wanted to recreate this feature in Super Mario Bros where jumping at a block from underneath while also being at the far edge nudges you away from the block instead of being stopped altogether.

Here mario is about to hit the block

[img=94163} Instead of hitting it and getting pushed down, he is shoved to the right. I can't think of any way to achieve this, so any help would be nice, thanks!

sorry second image got messed up here it is.
