A 13kg block of wood is at rest. A .400kg glob of putty is thrown at the block of w.The putty hits and sticks to the block. the block and the putty slide 15cm and then stop.initial v of putty?

Unknown. Everything after the collision depends on the nature of the friction between the block and the surface on which it slides. We have no way of estimating the energy dissipated as the 13.4 kg scrapes along for 15 cm before coming to rest, so we can't calculate the KE of the putty before the merger.

If a block weighs eight kilograms plus half a block what is the weight of a block and a half?
24 kilograms. I say this because 8kg plus half a block is a whole block. The half a block has to be also 8 kg making a whole block weigh 16 kg. Now 1 block (16kg) plus half a block (8kg) added together is 24kg
