A 2 kilogram wood block is launched up a wooden ramp that is inclined at a 30 degree angle. The block's initial speed is 10 m/s. The coefficient of kinetic friction of wood on wood is μk= 0.2.
A. Find what vertical height does the block reach above its starting point?
(m)
B. Determine what speed does it have when it slides back down to its starting point?
(m/s)
