For this problem,

Why for part (a) the solution is,

Is the bit circled in red zero because since the putty is released at a very small distance above the rod it velocity is negligible?

Also for part (d) the solution is

I did a computation of the initial and finial kinetic energies of the system and found:

##KE_f = \frac {KE_im_i} {2m_f} ## so I guess that's why the finial KE is less than the initial.

Many thanks!
