so i got the 48.4kg=M, but is this not the total mass of the system, so wouldn't the mass of the cylinder be M-m=48.4-0.3-48.1, which is still 48 when you round it to two significant digits, but i just want to make sure that I am understanding where all the variables are coming from. or am i...
im still confused with part B. my attempt:
sum of F in the mass= ma=mg-Ft
mg-ma=Ft
(0.3kg)(9.8m/s^2)-(0.300kg)(a)=Ft
But what is a? I am assuming its not "g" because the tension would decrease the acceleration. Also, do we need to take friction into account?
when substituting into I = 1/12M(L^2 + w^2), i understand that L= 1.2m but how did u come to the conclusion that w is also 1.2 m. I understand that if this were a square but its a plate
