Homework Equations
α = ω/t
τ = I*α
The Attempt at a Solution
CM = [232200*99 + 99/2*12500] / (107100 + 232200 + 12500)
= 67.102 m
τ = 43320*67.102 + 43320*(99 - 67.102)
= 4288680 N
α = ω/t
τ = I*α
τ = I*(ω/t)
ω = τ/I * t
= 4288680 / [107100*67.1022 + 1250*(67.102 - 99/2)2 + 232200*(99-67.102)2] * 28.3
= 0.1688
