Toaster Chord Tension Problem

    1. The problem statement, all variables and given/known data
    A 1.26kg toaster is not plugged in. The coefficient of static friction between the toaster and a horizontal countertop is 0.395. To make the toaster start moving, you carelessly pull on its electric cord. For the cord tension to be as small as possible, you should pull at what angle above the horizontal?

    2. Relevant equations
    Fantastic 5

    3. The attempt at a solution
    I have tried using a regular F net equation, but was told that I need to derive somewhere?

    You need to draw a free body diagram and be careful to consider x and y components of the vectors.

    What is the y component of acceleration (therefore the net y component of force divided by mass)?

    I have tried this, but it lead to me cancelling out my unknown? Is there a specific method/procedure that I should follow?

    You did it wrong. Try again. Post vertical and horizontal equations here before you cancel anything out.
