1. The problem statement, all variables and given/known data 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 centre of the turntable. Show that the acceleration is a=-Rω^(2)r̂ .Find the components of the block's acceleration parallel and vertical to the inclined plane. Finally, find the minimum angular velocity needed to keep the block from sliding down the face of the wedge 2. Relevant equations a=-Rω^(2)r̂ 3. The attempt at a solution I'm really not sure how to start this problem- I know I need to use cylindrical coordinates with z constant but apart from that, I'm really stuck. Any help would be much appreciated!
