- Homework Statement
- A disk with a slot rotates on a horizontal plane about a tree that passes through its centre, while a slider ##P## of mass ##450 g## moves on the slot.

The disk is at rest and the slider is in the position depicted in the picture when an angular acceleration of ##40 \frac{rad}{s^2}## is applied to the disk with a clockwise direction.

Find the horizontal force exerted on ##P## by the slot when the motion is started and the inicial acceleration of ##P## with respect to the slot.

- Relevant Equations
- Newton's equations

What forces are exerted by the slot on the slider? You have a normal force since it's inside it, and that's the only force that I can imagine. But then? I think about the pseudo-forces since it's on a rotating reference frame (centrifugal force, Coriolis force, Euler force), but those forces are not exerted by the slot itself.
