Exactly!
My professor is essentially saying that the force of friction between the block and ramp is exceeding the other force on the block. Therefore, the force of friction is causing the block to move. This is impossible; the frictional force cannot do this.
At least I feel vindicated...
Thanks for your help!
UPDATE:
I talked to the professor. She said that the only time there is zero movement is when the frictional force is equal to (not greater than) the forces creating movement. If there is any difference, there is movement acceleration.
So, no extra points for me...
Hello! Thanks for responding.
I get that. But, I don't think this is a problem where you can just plug the numbers into the formula. I think it's one of those special cases where you have intermediate values that prevent acceleration.
With no friction:
a = [(m2)g-(m1)(g)(sin@)] / [m1+m2]...
Hello! First time, long time!
This is kind of a long post. I did what I could to keep it clear. TYIA!
I was marked totally wrong on a test question and I think I may have been correct. I'm trying to get my ducks in a row before I ask the professor to review this with/for me. Everyone in the...
