Explanation / Answer

v/radius = omega = rad/s

4.1/2.6 = 1.576 rad/s

angular momentum = Inertia x omega = kg-m^2/sec

We have found omega = 1.576 rad/s

We need to solve for inertia.

Inertia for this would be taken as mr^2 = 47 x 2.6^2 = 317.72 kg-m^2

units for inertia are (kg-m^2)

omega x inertia = angular momentum

1.576 x 317.72 = 500.726 kg-m^2/sec
