(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A basin surrounding a drain has a shape of a circular cone opening upward, having everywhere an angle of 35 with the horizontal. A 25 g ice cube is set sliding around the cone without friction in a horizontal circle of radius R.

(a) find the speed the ice cube must have based on r

(b) is any piece of data unnecessary for the solution? suppose R is two times larger

(c) will the required speed inc, dec, or stay constant? If it changes by what factor?

(d) will the time required for each revolution inc, dec, or constant? by what factor if it changes?

(e) do answers to part c and d seem contradictory? Explain how they are consistent

2. Relevant equations

Fc=mv^2/r

ac=v^2/r

3. The attempt at a solution

I don't know where to start. I wasn't even able to come up with a FBD

guessing if I use (SIGMA)Fr=mv^2/r

you can solve for speed for part a but what would be on the other side.

i really have no idea
