A cyclist moves by pedalling along an elevated horizontal track. At the track’s end, he continues horizontally into the air and lands on a track that is $2.0\,\text{m}$ lower vertically. While in the air, the cyclist covers a horizontal distance of $6.0\,\text{m}$. Air resistance is negligible. What is 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$15\,\text{m s}^{-1}$
