Explanation / Answer

a) I= ML2/3 + mL2 (Option D)

b) We treat the bullet and rod as our system. Since no external torques act on them angular momentum is conserved. L =Lf - Li = 0

Lf = Li

Now   Li =mDVsin

and Lf =I =(M/3 + m)L2

Since Lf = Li

mDVsin = (M/3 + m)L2

= mDVsin/(M/3 + m)L2

=DVsin/(M/3m + 1)L2
