Homework Statement
There is no friction between any surfaces mass is known. Find acceleration of the blocks.
Homework Equations
F=ma
The Attempt at a Solution
I'm almost certian
Amx=g sin θ
AMy=0
Yes, these look correct.Amx=g sin θ
AMy=0
That would be true if the wedge were fixed. But imagine if the wedge were not only frictionless but extremely light. The block would be almost in free fall.Amx=g sin θ
For the block, the x direction is parallel to the incline. So, free fall acceleration would have an x-component of magnitude g sinθ.That would be true if the wedge were fixed. But imagine if the wedge were not only frictionless but extremely light. The block would be almost in free fall.
I had not picked up that x was defined as parallel to the slope.For the block, the x direction is parallel to the incline. So, free fall acceleration would have an x-component of magnitude g sinθ.
Nor had I, especially since x is specifically drawn in his solution diagram as being the normal horizontal axisI had not picked up that x was defined as parallel to the slope.
