on the moon they would hit at the same time because there is no air resistance and the acceleration due to gravity is independent of mass for small objects (e.g. non-planet sized objects)
since air does exist on earth, the brick will most like land first because weight does matter when dealing with a force, such as air resistance (but so do other things such as surface area)

acceleration due to gravity is the same for all objects regardless of mass (9.8 m/s^2). therefore when there is no outside forces interfering on both objects they will land at the same time(ex: air resistance).However to determine which one would land first when it isn't in a vacuum would be extremely difficult. you must add together many factors and see which one would have the least interference and would therefore fall faster.If there is no upward force(updraft) it seems the coin would land first since it has a smaller surface area for it to build up friction against the air, but if there is an upward force the brick would seem to land first since it has a greater mass than the coin and therefore that force would have a smaller affect on it.

The brick will hit first. Initially they will fall at the same rate, but the penny reaches its terminal velocity of about 66MPH in about 100 ft of freefall (caused by wind resistance). I don't know the results of any tests of the terminal velocity of a brick but I estimate it to be around 300 MPH.

the brick should land first as its shape is not aerodynamic. Gravity does have the same pull on all objects, but if one object is more aerodynamic than another then the one that is less aerodynamic will hit first. air should catch the coin a little better than it would a brick

The Coin, because we know that if you drop both, the brick is bound to hit someone in the head therefore stoping downward progress.

the brick newtons laws and famous pertain to experiments of same shape but when diff. shape occurs it would be diff. i.e
paper unfloded if you drop it would take a long time to hit groun but crumpled up faster, though if you drop licence plate it is the same

They would both land at the same time.

They would both hit at the same time with the acceleration rate of 9.8m/s/s without air resistance.

I think you know the answer to that one. They both land at the same time.

If air resistance is negligible, then they would land at the same time.
