A bicycle is released from point \( A \) with an initial velocity of \( \mathrm{v}_{0}=0 \mathrm{~m} / \mathrm{s} \). The bicycle does not leave the track and travel through point \( \mathrm{C} \). If the \( \mathrm{h}=30,000 \mathrm{~cm} \) and \( \mathrm{r}=10,000 \mathrm{~cm} \). Calculate the \( \mathrm{H}(\mathrm{m}) \) and the velocity of the bicycle at point \( \mathrm{C} \) \( (\mathrm{km} / \mathrm{h}) \) ? Assume that the surface is smooth and neglect the air resistance.
