a) max angular acceleration?

b) max restoring force?

for a... I vound that the max velocity is 0.817m/s

[tex]\omega=\frac{v}{r}[/tex]

[tex]\omega=\frac{0.817m/s}{1m}[/tex]

[tex]\omega=0.817rad/s[/tex]

[tex]\alpha=r \omega ^2[/tex]

[tex]\alpha=1m * 0.817^2[/tex]

[tex]\alpha=0.668rad/s^2[/tex]

I know that's wrong but why?

for b...

I just multiply alpha by the radius to get acceleration then multiply that by the mass.
