A 2.0 kilogram 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 µk .200.
Part A: Find what vertical height does the block reach above its starting point?
Part B: Find what speed does it have when it slides back down to its starting point?
