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.
y=y0 + v0t + 1/2at^2
The Attempt at a Solution
a) y=y0 + v0t + 1/2at^2
0.54m = (0.5)a(3s^2)
T-(0.3kg)(9.8m/s^2) = (0.3kg)(0.12m/s^2)
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!!
