sorry i couldn't fix the image properties but thank you so much for helping me!
A top-loading washing a spin cycle that rotates at frequency f. The spinning drum that holds the clothes has a radius R, and a particular piece of clothing has mass m. (Assume that the clothing is flattened tightly against the vertical inner wall of the drum, so that the entire piece of clothing can be considered to be located at radius R from the center of the cylinder.) Express your final answers... bullet ONLY in terms of f, R, m, g, and exact mathematical constants bullet in SIMPLEST algebraic form Find an expression for the magnitude of the wall's normal force acting on the piece of clothing as the drum spins with frequency f. Show your work. Find an expression the minimum coefficient of static friction that will allow a piece of clothing to remain stuck to the inside wall of the drum, without sliding downward toward the bottom of the tub. Show your work.Explanation / Answer
here force f = mv^2/r
v = 2pir/T
f = 1/T
v = 2pirf
f = m*4pi^2r^2f^2/r
f = 4pi^2*m*r*f^2
