A cyclist moves along a raised horizontal track. At the track’s end, he leaves it travelling horizontally through the air and lands on a track that is vertically $2.0\ \text{m}$ below. While in the air, the cyclist covers a horizontal distance of $6.0\ \text{m}$. Air resistance is negligible. Determine the horizontal velocity $v$ of the cyclist at the end of the upper track?
- A$6.3\ \text{m s}^{-1}$
- B$9.4\ \text{m s}^{-1}$
- C$9.9\ \text{m s}^{-1}$
- D$15\ \text{m s}^{-1}$
