im having alot of trouble with this one also:

A 2.0 kg wood block is launched up a wooden ramp that is inclined at a 30 degree angle. The block's initial speed is 10m/s. The coefficient of kinetic friction of wood on wood is .200.
What speed does it have when it slides back down to its starting point?

PROBLem is solved folks, thanks for the help HallsofIvy

is the second question asking for the final velocity or the initial?

Well, you said "What speed does it have when it slides back down to its starting point?" It slides up the slope, then back down. Assuming that by "final velocity" you mean its velocity as it passes that initial point the second time, yes, that is what is asked.
