If an object is dropped from a tall building and hits the ground 3.0 s later, what is the velocity of the object when it hits the ground? (Remember that the velocity is downward)

i got -29m/s
is this correct?

• physics -

correct: -9.8*3

• physics -

I got -29.43m\s but that's not taking air resistance Into consideration.
