We'd like to find the mass of these objects.
00:07
First, we need to find the slope of each line.
00:13
And remember, the slope represents 1 over m.
00:20
So, for example, at our force is equal to 2 for a number of rubber bands, we have an acceleration of 3 meters per second squared.
00:31
And at f is equal to 4, we have 6 meters per second squared.
00:37
Now let's look at our slope of our line 2.
00:41
That's our change in acceleration over change in force.
00:45
Or our 6 minus 3 over 4 minus 2.
00:49
This gives us 3 over 2, or 1 .5.
00:56
But this is also equal to 1 over mass 2.
01:00
So we can rearrange to solve for mass 2...
