Homework Statement

Hi, I am doing this lab this week, but before I do it I have a few questions. ( it has to be completed in class so I want to be prepared). First, these are the three pages of the lab questions:

On page 2, in the table. To find the total hanging weight and acceleration, for example for the first one , is my answer correct?: http://i1076.photobucket.com/albums/w457/Hbjoi_Hggo/image.jpg1_zpsgwgpizad.jpg

Homework Equations

The Attempt at a Solution

On page 2, in the table. To find the total hanging weight and acceleration, for example for the first one , is my answer correct?: http://i1076.photobucket.com/albums/w457/Hbjoi_Hggo/image.jpg1_zpsgwgpizad.jpg

My other questions are for #2 and #3 in my lab, for #2 is the answer a) and for #3 is the answer b) ?

My last question is for #4 in the lab, it says to make a weight vs acceleration graph. I know that the slope of the line means the total mass so that will be my answer for #6, but when making the graph does the weight go on the x-axis and the acceleration on the y ?

All looks good.
For #4, it does not really matter which you assign to which axis, provided you use the appropriate method for finding the slope and interpret it correctly.
It is usual to put the independent variable (the one you control) on the X axis, and the standard regression equation for finding slope assumes you have done it that way. So then you just have to think whether the total mass is the slope or the inverse of the slope.
