Hey everyone, I'm having trouble finding velocity on a straight line position/time graph. Every single equation I do ends up with a different answer, which doesn't make sense because it's a straight line.
I know the equation is
Vf-Vi/Tf-ti
The answer to this question is 1.4m/s N
Example:
45-25/28-16= 1.666666m/s Wrong answer. I'm just taking these from the graph by the way.
25-20/16-14= 2.5, completely different answer.
Could someone please explain what I'm doing wrong? I'm calculating the slope which seems to change with every calculation that I do, which I understand is wrong.
