A box rests on a plank that is inclined to the horizontal. As the angle between the plank and the horizontal increases, does the component of the weight of the box parallel to the plank increase, decrease, or remain the same? Please just answer
Suzanne, you are going to have to think this out. Fill this table out:
Theta SinTheta

THe question I asked, is as theta increases, what does Sine of Theta (SinTheta) do?
That is the answer to your question.
