 Homework Statement
 A weight starts from rest, what is its velocity after falling 0.82m? Use energy considerations.
 Homework Equations

M = 4.5 kg
R = 8.5 cm
Ip = 3 * 10^3 kg m2
rp = 5 cm
m = 0.6 kg
I've done this exercise twice now, the answer is 1.4m/s but I get 1.64m/s. It's too far off to be rounding error.
1. I don't use energy consideration, because I don't have a clue how that would work.
2. I still need to know what's wrong with my current way of solving this.
Any help is appriciated :)
