Angular momentum is given by
[tex]L = I w[/tex]
here we have
I = moment of inertia of wheel
[tex]I = \frac{1}{2}mR^2[/tex]
[tex]I = \frac{1}{2}*3.2*0.27^2[/tex]
[tex]I = 0.117 kg*m^2[/tex]
angular speed is given as 1500 rpm
[tex]w = 2 \pi f[/tex]
[tex]w = 2 *\pi * \frac{1500}{60}[/tex]
[tex]w = 157 rad/s[/tex]
now angular momentum is given by
[tex] L = 0.117 * 157 = 18.4 kg*m^2* rad/s[/tex]
