Ok, for the circular motion, where we are suppose to have 0 acceleration,

this is the problem i have

My question ask for mass of the washers and paper clips by equating Fc to Fg,

and I am given the # of washers,

The radius

and the mass of the stopper.

and the period

now it ask me for mass

how do i find this?

i kno that

Fc = mv^2/r

or

Fc = 4pi^2rm/T^2

and

Fg = mg,

but how do i do it?

i can't seem to figure it out,

even after i figure out the speed, it doesn't help, i have 2 unknowns...The

Fc, and the mass...

help please?

Incase this helps, i am swinging the tubber sopper, with a tube, and below the tube is the paper clip to keep my distance so i kno i am swinging at a constant speed, then at the end of string is my washers for the mass.
