HELP ME WITH PHYSICS!!!! (SIMPLE)

[From: ] [author: ] [Date: 13-03-06] [Hit: ]
I will just rewrite it.1 second - 9.2 seconds - 19.3 seconds - 29.4 seconds - 39.5 seconds - 49.......
I have a question from our science textbook that I do not understand. The question is;

Suppose another object of the same size but with a greater mass was dropped instead. How would the speed values change?

Here is the line graph that goes along with it. Since I am on the computer, I will just rewrite it.

Motion of an object in free fall:

0 seconds - 0m/s
1 second - 9.8 m/s
2 seconds - 19.6 m/s
3 seconds - 29.4 m/s
4 seconds - 39.2 m/s
5 seconds - 49.0 m/s


Please help! I do NOT understand at all. Tell me the answer and give a short explanation please!!

-
The mass of the object has no significance in the speeds.

Your acceleration in this case is a = v/t which is 9.8 m/s/s

The only time you'd see a change is when you're dealing with some form of friction such as air. The above assumes friction-less mediums.
