In Survival mode:

Cactus	Yes	No	Yes
Arrow	Yes	No	Yes
TNT	Yes	No	Yes
Pickaxe	Yes	Yes	Yes

In Creative mode:

Destroyed by	Drops: Minecart	Hopper	Hopper Contents
Cactus	Yes	No	Yes

TNT	No	No	No
Pickaxe	No	No	Yes

In testing with cactus, there was a possibility that the hopper might land on the cactus and being destroyed. I used a hopper under the rail to try to grab the drops before this could happen. The hopper successfully grabbed the minecart and/or hopper contents, but never a hopper.

To test with an arrow in Creative, you have to initially aim at something else, then slide to target the minecart with hopper while holding down the use control.
