mass, but i can't calculate v - I've already tried this many times...i guess the question comes down to being able to calculate v.

that gives the acceleration...not force.

I used Fcos(20) = mg -> which is just a version of f = ma I can't find equations for the magnitude of the centripetal force or the velocity...which is very annoying. I've been looking in my book for a while now.

centripetal, but i don't know the velocity, so I can't calculate that either...

I did, but I'm still pretty much clueless.

i don't know how to calculate it. And I mentioned it merely because I THINK it applies.

Homework Statement A rock of mass 5.5kg is hanging from the ceiling moving in uniform circular motion. The radius of the orbit is .8m. The angle of the rope in comparison to if it were hanging straight down is 15 degrees outward. What is the magnitude of the force of the cord on the...
