non slip ball down an incline of theta!
A uniform solid sphere rolls down an incline without slipping. If the linear acceleration of the center of mass of the sphere is 0.16g, then what is the angle the incline makes with the horizontal?
F=ma T=I(alpha) I=(2/5)MR^2 a=r(alpha)
I know that you have to use the first two equations. I made a free body diagram of the bowling ball, but i am confused about the first equation F=ma. is F the force of kinetic friction? how am i supposed to solve for the kinetic friction? is it equal to Mgsin theta where M is the mass of the bowling ball? then there would not be acceleration. I am confused
