Who can answer this? Should'nt be too hard...?

Question

A single sheet of 8.5 X 11 piece of paper dropped from ten feet high at the same time as a five pound rock; How can you get the paper to the ground at the same time as the rock?

Put a book under the paper. You can do it at home!! watch the paper fall at speed!

Answer 1

make the surface area of the paper the same as the surface area of the rock by crumpling it. due to someone's law, all objects fall at teh same rate (I think it was Galileo), but there is also some air drag effects, which depend on the surface area.

For this reason, if the objects had almost teh same surface area, they would fall at the same rate and air drag would affect them both about the same amount, so they should hit the groudn at the same time.

Hope that helped

I guess most people that answered this aren't familiar with Galileo's statement that all objects fall at the same rate, regardless of their weight. The only reason that this isn't completely true on Earth is because of the drag effects caused by the air in the atmosphere.

By surface area, I mean the area of the bottom of the object

Answer 2

you tie a five pound rock to the piece of paper and drop the paper and rock with the normal rock! :)

Answer 3

Conduct the experiment in a vacuum or wrap the rock in the paper

Answer 4

drop them in a vacuum. They will fall at the same rate, or wrap the paper around the rock then drop them.

Answer 5

Just fold it as much as you can to get the least air resistance possible. The free fall acceleration is the same for all bodies.

Answer 6

Crumple up the paper into a ball.

Answer 7

tie the rock and paper together

Answer 8

Conduct the experiment in a vacuum.

Answer 9

go to the moon and drop it

Answer 10

put them together then drop them
