All things that someone with Spider-man level strength should be able to do easily but I'll admit that Spider-man himself is never depicted doing similar things with the same amount of ease (even though he should) but that is likely because writers try to play up his speed and agility rather then his strength... and his durability isn't even close to Morluns so he would risk injury.
Anyway on the whole "Spider-man said Morlun hit hard then the Hulk arguement," I'd like to point out that Spider-man also said that Captain America hits with the strength of an Atom Bomb, and that he himself had 40x human reflexes... he is a no good liar. 😄
