A wedge with face inclined at an angle theta to the horizontal is fixed on a rotating turntable. A block of mass m rests on the inclined plane and the coefficient of static friction between the block and the wedge is μ. The block is to remain at position R from the center of the turntable, as shown in the attachment. Find the components of the block's acceleration parallel and vertical to the inclined plane.
a=-Rω^(2)[itex]\hat{r}[/itex]
I have been struggling to get to grips with this question for a while now. I don't understand how the acceleration is pointing in the opposite direction of the position vector r, which has a z axis component although there is no displacement in that direction. Have I interpreted the polar coordinates wrongly? Any insight would be greatly appreciated. Thanks.
