1. The problem statement, all variables and given/known data A light string is wrapped around a solid cylinder and a 300g mass hangs from the free end of the string. when released, the mass falls a distance of 54cm in 3.0s. a) Calculate the tension in the string. b) Calculate the mass of the cylinder. 2. Relevant equations y=y0 + v0t + 1/2at^2 I=mr^2 α=a/r T-mg=ma F=ma τ=Iα τ=rF 3. The attempt at a solution a) y=y0 + v0t + 1/2at^2 0.54m = (0.5)a(3s^2) a=0.12m/s^2 T-mg=ma T-(0.3kg)(9.8m/s^2) = (0.3kg)(0.12m/s^2) T=2.979N b) τ=Iα τ=mr^2α Fr=mr^2α F=mrα I'm not sure if thats right for a), I feel like I'm missing something.... I'm very confused for b). I have been playing around with the equations, as you can see above, but I keep going in circles and I feel like I don't have enough information. Thanks in advanced for any help!!
