Why do you think that if you drop a pound of each from a high building, the brcks will land first? You can try this experiment yourself.
I have done that experiment, and yes, the constant 9.81 m/s/s will not prevent the bricks from hitting the pavement first. I have also done the experiment in a vacuum tube, and the feathers and the steel balls did hit the bottom at the same time.
"do they weigh more". Let's not confuse the issue, we were talking about mass, not weight.
If you think that you are so smart, I challange you to a steel cage match. You can arm yourself with a pound of cotton, and I will use one pound of bricks.
I'll take the challenge, not doubt intelligence will prevail and I will defeat you and your heavy brick gunnery . Regardless, you can't move very well given your age, your knees, your MASS, your lack of peripheral vision, not to mention that one string of hair that you use to wrap you head thta always falls in your eyes when you physically exert yourself! Interestingly, your mass is greater than most, but yourdensity is much lower than most. Had you been on the Titanic that night, you would have floated just fine, and would have died from hypothermia, not drowning.
Given a building of a height of 99.75 meters.
A brick dropped
from the ledge will take 4.472 seconds to hit your head, and, at the time of impact, will have a velocity of 43.87 m/s.
That should tell you something about yourself, but what?
