A block of mass m = 0.29 kg slides with initial velocity v0 m/s along a frictionless surface (as in the figure). The block next slides through a region of length d = 0.2 m with kinetic friction. After passing through the friction region, the block slides up a curved ramp until momentarily coming to rest at a height h above the level surface. If the kinetic friction coefficient μk = 0.07 and the block reaches height h = 0.15 m above the initial level, what was its initial velocity v0? Express the answer in m/s but enter only the numerical part in the box.
